Last night in the Carribean, I was looking at the sky at about 8PM EST, and I noticed this really tiny object moving pretty fast from left to right, just between the two stars in the photo. It's very difficult to see and after a while it just disappears.

Somebody told me they had seen it a few days ago going the same exact direction and more or less at the same time.

Can anyone identify this moving object?

I'm including the picture of where I saw it, but you can't see the object. I didn't bother taking a picture while it was moving because it's so tiny that I had trouble finding it myself.

Also, is there a way for an amateur like myself to identify these objects?


Top 10 Night Sky Objects for Amateur Astronomers

Although there are thousands of astronomical objects worth observing in the night sky, all astronomers, both amateur and professional alike, will tell you that they have their own personal favorites. These might include lingering early memories, such as the first sighting of the Milky Way‘s largest globular cluster, Omega Centauri, or the first splitting of a difficult binary star system, such as observing the double star Albireo in Cygnus, whose brighter yellow star presents a striking contrast to its fainter blue companion. Whatever the case may be, the following list looks at ten celestial objects most astronomers agree are worth a second look.

It is possible to spend a life time observing the Moon, and still discover something new every time you observe it. The play of light and shadow, the amount of illumination, and the libration of the moon can sometimes obscure some features, but bring them sharply into focus at other times. A good time to observe the moon is during daytime when it is visible, and quite often, you will discern detail that is not visible at night.

The moon is an excellent training ground for new observers, since many features become visible only during some illuminations, but mostly because the use of the correct magnifications is required to see some features. High magnification are not always the best option, so use the moon to practice using different magnifications under different conditions before you venture further into the solar system, and beyond. One thing is certain, though, you will keep coming back to moon!

The Planets

Finding Mars is one of the most rewarding experiences any novice star gazer can have, and while it first may look nothing more than a small reddish disc, with a bit of practice even a small 4″ telescope can reveal tantalizing detail, such as the Red planet’s darker regions, and the formation, and subsequent disappearance, of its polar ice caps as the seasons change there. If you don’t have a go-to scope, Mars offers an excellent opportunity to learn your way around the night sky, since during certain times of the year it is easy to confuse the Mars with Antares located in the constellation Scorpius, which is a giant red star.

Venus also displays phases, just like the Moon, and although it may sometimes be difficult to obtain a fine focus on Venus, with good optics, and some practice with the fine focus control, it is possible to view the phases of the planet as its illumination from the Sun changes. Venus may not offer any detail other than it’s phase, but you will want to see it again and again.

The King of the planets always offers a rewarding viewing experience, since the detail on its colorful bands is forever changing. However, fine detail is only visible in larger amateur instruments, but even modest equipment, such as the photo taken by the 130mm (5″) telescope opposite, will reveal the equatorial bands and the four Galilean Moons as they weave their way around the gas giant.

Of particular interest is the Great Red Spot on Jupiter, which is visible during good seeing conditions with even modest equipment. Once you start tracking the movement of the Spot, you will want to return to Jupiter for as long as it is visible. Since its discovery, the Great Red Spot has moved more than a 1,000 degrees, and at one point, it was even out of sight on the far side of the planet. See how well you can track this storm (that is larger than the earth) on the “surface” of Jupiter.

When Saturn’s rings are tilted with respect to our line of sight, the planet offers the most spectacular sight in the entire solar system. Even modest equipment, such as a 4″ telescope will reveal the splendor of the ring system, but be aware that you may be disappointed at your first sighting of the planet. The ring system changes its inclination to our line of sight, and at certain times the rings disappear altogether when they are face-on to earth. The rings are only a few tens of kilometers thick, so wait for a few months, and look at Saturn again- you will be glad you did! The “gap” in the rings to the right of the planet is caused by the shadow of the planet as it falls across the ring system.

Star Clusters

Pleiades Star Cluster (M45)

Also known as the “Seven Sisters”, this small cluster in the constellation of Taurus consists of several dozen stars, of which only a few are visible without optical aid. However, even a small telescope (2.4″ to 4.5″) will reveal most of the stars in the cluster, which incidentally, are hot blue stars of roughly the same age, and composition. It is best to view this cluster from a dark site, and at a low magnification. Higher magnifications reduce the field of view, which means that most of the cluster is lost to view. Lower magnifications and dark skies also make it easier to see the bluish haze, which is the dust and gas in a large cloud that is moving across the cluster.

The Andromeda Galaxy (M31)

At 2.5 million light-years from Earth, Andromeda may be our closest neighbor in the Local Group of Galaxies, but it will present you with your first real test in finding dim objects. As with other colorful objects, photos of the Andromeda Galaxy are the result of exposures through different filters, but in your telescope, it will appear as a large, fuzzy patch without any real detail. However, the real reward will be in having found it in the first place. The key to finding this large spiral galaxy is finding the constellation of Pegasus first, and then from there you can find it located in the adjoined constellation of Andromeda using a good star chart or atlas. Once you have it in your sight, though, you can appreciate the fact that you are watching a huge galaxy that is approaching you at a speed of 125 kilometers per second.

The Orion Nebula (M42)

Because Orion lies almost on the celestial equator, it is visible from both hemispheres, and is one of the most recognizable shapes in the entire sky. The “waist” of the Hunter consists of three stars, and hanging from the Belt of Orion, as it is also known, are a further three stars that form Orion’s Sword. The “star” closest to the waist is in fact a small cluster of stars, but the second one down is a large nebula known as the Orion Nebula that with a small scope and steady gazing will reveal a beautiful bluish tinge. This beautiful nebula is 25 light years across, contains over 1,000 young stars and shines with an apparent magnitude of +4.0. At a distance of 1,300 light years, it is also our nearest star-forming factory, and also contains a cluster of young stars called the Trapezium Cluster.

The Ring Nebula (M57)

The Ring Nebula in Lyra may be as difficult to find as Andromeda, but it will reward you in an unexpected way. It is one of only few objects that shows anything close to its true color in a telescope, and you will want to look at it for as long as you can. It is located between two rather bright stars, Sheliak and Sulafata, in the constellation Lyra, and you need to increase the magnification of your eye pieces as you close in on it. Higher magnifications tends to “darken” the background, so when you get it right, the Ring will leap out at you. Enjoy the sight the search will have been well worth the effort!

The Crab Nebula (M1)

Also known as M1, being the first item in the Messier catalog, this nebula got its name from Lord Rosse, who sketched it after viewing through his 72-inch telescope, which happened to be largest telescope of its kind in the world in 1845. In the original sketch, the nebula looked like a crab, hence the name Crab Nebula. In reality, the nebula is the remains of a star that exploded as a supernova in 1054. Chinese astronomical records identify it as the “guest star”, and also mentions the fact that it was visible during the day. Today however, it can only be seen at night on the southern horn of Taurus, which is a constellation to the southeast of Orion. For the best viewing, use a magnification of around 200 times.

There are many more…

The few objects on this list represents a minuscule fraction of what is visible with an amateur instrument, but all of the above items have their own particular challenges. However, challenges are only stepping stones, and as you learn the sky and develop your observing skills, you will eventually start to “discover” other treasures on your own. Enjoy the journey!


A Universe to discover

Star-hopping really is fascinating.

Not only are you recognising the patterns of constellations, you’re also learning about star distances, star colours, ages and names.

You’ll find that the whole of the night sky is an amazing mixture of space, time, history, science and world cultures.

It’ll lead you off on all sorts of paths and you’ll learn things that will amaze others.

Not to mention the basic reason – you’ll know what you’re looking at.

Now, you don’t need any optical instruments to begin star-hopping, but it does help to have a few things handy to make your evenings more enjoyable.

Firstly, let’s deal with the comfort aspect.

Even in the summer, it will probably get chilly – at the very least – so wrap up warm.

Then, to get as comfortable as possible, set up a deck chair or sun-lounger – maybe we should call it a star-lounger in this case.

Just before you pop outside to try some real star-hopping, there are a couple of final useful things to have with you: a star chart or atlas, plus a red torch to see the charts, and also where you’re going, without ruining your night vision.

And don’t forget a flask of tea and a few biscuits for when you fancy a break.

If you’re new to star-hopping, position your star-lounger north-south and sit with your feet pointing north.

This will put you in an ideal position to see several key star-hopping points: the Plough, the North Star and the constellation of Cassiopeia as they’re all around the north part of the sky.

Why not practise star-hopping using the example shown below? Remember, take it easy, and you’ll be finding your way around the sky in no time.


What did you see?

Here’s a quick guide to some strange lights in the night sky, and what they might be.

Steady moving lights, flashing each second, possibly green or red sometimes very bright white lights.

It’s likely to be an aircraft. This is probably a trivial case as most people are aware of what planes look like at night. Near airports, planes can have very bright landing lights turned on that can drown out any flashing beacons.

Steady moving light high in sky with no flashing. Moving slowly. Seen after sunset or before sunrise. Can be very bright, but usually quite dim. May disappear almost instantaneously.

You may have seen an artificial satellite. There are hundreds of satellites in the sky, normally only visible in the night sky after sun-down, when the light is still shining on them. The sudden disappearance happens when it moves into the Earth’s shadow. If the light is very bright, it is likely that you have just seen the International Space Station, quite a common sight in our skies these days.

Orange flickering light, floating around 50 to 100 metres above the ground. Light may dim slowly after a few minutes.

You have possibly seen a Chinese Lantern, a small, inexpensive hot-air balloon made out of paper and wire. Chinese Lanterns have become very common around the country at celebrations, Halloween and New Year’s Eve.

Steady bright light. No apparent movement. May be close to horizon or visible in the southern sky. Much brighter than surrounding stars.

It’s possible you have seen Jupiter or Venus, two surprisingly bright planets at certain times of the year. After the Moon, these two objects are the brightest objects in the night sky.

A very bright point of light in the sky. It lasts momentarily, then disappears again. It may move slowly. So bright you might even see it during the day.

You may have seen an Iridium Flare, essentially the reflection of a low-orbit Iridium satellite, originally used to provide satellite mobile communications. The reflections can be surprisingly bright.

Very bright green or red light in the sky, 200 metres or so above ground. Appears to move very slowly.

You may have seen an emergency flare. This is a very bright firework, shot up in the sky as a distress signal to nearby shipping. In Ireland, flares are often sent up during celebrations like the New Year.

Fast moving bright object. May travel a large distance across the sky in a split second. Possibly a greenish colour associated with the event.

You may have seen a fireball. This is a rocky object from space that has collided with the Earth’s atmosphere, heating up and exploding on impact. It may also be a satellite re-entering the Earth’s atmosphere. Such an event is worth noting! You should make a note of your observation with the International Meteor Organisation.

Strange diffuse lights, illuminating clouds. Moving rapidly, possibly rhythmically. There may be more than one light in the sky.

You may have seen the effect of searchlights shining up on clouds. Local festivals and event organisers sometimes use searchlights to attract attention to their shows at night.

Other sightings may have arisen from light reflections, optical illusions or mistaken identity. It may be that the witnesses were very tired at the time or under the influence of drugs or medication, or they may have been the subject or originator of a deliberate hoax. The key thing is to always discount the more mundane answers before ever jumping to improbable conclusions.


How to identify that light in the sky

Generally speaking, we tend to frown on rage/meme/ images, however, this one is a classic. Thanks, OP.

Can you sticky this image at the top of this subreddit?

No problem! Thanks for bending the rules :D

Awesome, the only thing I was wondering about: Is it true that only stars and no planets are fuzzy?

It is! (maybe not so much fuzzy as "flickery") I use it as a guide for when I am looking for planets without a telescope. You will notice that planets simply reflect light so it appears to be "solid" (like when you look at the moon) and when you see stars they tend to flicker a combination of red/white/blue/etc.

EDIT: Removed last sentence due to "Reflection vs emission".

To help understand why a planet's larger disc makes the difference in why it twinkles less, imagine you represent the stream of photons coming into your eye by placing a number of beads on a table in a circular pattern. For a star, you would place 1 single bead to represent the tiny point of light. For a planet, you would make a small circle filled with beads, let's say you place down 20 beads to make a small filled circle. You can't actually see this difference with your eye, but it is important and I'll explain why.

Note the approximate center point of each of your two bead-objects. Now, to simulate the effect of atmospheric distortion, you would move each bead from its initial position by just a small amount in a random direction. Do this for each bead, on both the "star" and the "planet" beads, by the same amount for each, but changing to a new random direction each time you move a bead.

Assuming all your bead movements were truly random, what you'll most likely end up with is a larger, more spread out, slightly less-circular planet and a star that hasn't changed shape but instead has actually moved. It's these small erratic movements that our eye detects as twinkling. The planet, on the other hand, doesn't appear to move far from its center point at all, due to the random nature of adding up all the many random interactions they will tend towards averaging themselves out. Instead it just appears to get a bit larger and fuzzier, But it's still too small for our eye to make out any of its shape, the only visible difference from a star is that it's not twinkling the way the stars are.

Technically planets can "twinkle" a bit too, they just do so much less dramatically than stars and it requires a very disruptive atmosphere (and even then stars will still twinkle better). Most stars are so far away that they are very close to being idealized point-sources of light with zero dimensions, they will twinkle easily with only minor disruptions. Planets, on the other hand, actually have a visible disc that is easily made visible in a low power telescope or binoculars. The difference is not noticeable from the naked eye, but the light being more spread out to begin with means they are much less affected by the atmospheric distortions that cause twinkling, and the eye can perceive that.


Sky 1: Objects in the Sky

To observe and describe what the sky looks like at different times to identify objects in the sky and recognize changes over time to look for objects that are common to the daytime and nighttime sky.

Context

This lesson is part of a four-lesson series in which students observe the daytime and nighttime sky regularly to identify sequences of changes and to look for patterns in these changes. At the K-2 level, learning about objects in the sky should be entirely observational and qualitative. The priority is to get students noticing and describing what objects in the sky look like at different times. (Benchmarks for Science Literacy, p. 62.)

The sun, moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described. Ideally, students should engage in direct observation of both the daytime and nighttime sky throughout this lesson series. However, the recommended Internet resources can be helpful to enhance student experiences, or if opportunities for direct observation are limited. This investigation requires that observations be ongoing, so that students can look for patterns over time. As children become more familiar with objects in the sky, they can be guided to observe changes, such as night and day and the seasons.

In this first lesson, students will investigate objects in the daytime and nighttime sky. This investigation should be confined to observations, descriptions, and finding patterns. Attempting to extend this understanding into explanations using models will be limited by the inability of young children to understand that earth is approximately spherical. Children at this age also have little understanding of gravity and usually have misconceptions about the properties of light that allow us to see objects such as the moon. (Benchmarks for Science Literacy, p. 336.) Thus, these topics should be avoided.

In Sky 2: Shadows, students explore making shadows and tracking the movement of an object over the course of a day.

In Sky 3: Modeling Shadows, students construct models to demonstrate their understanding of shadows.

Sky 4: The Moon has students drawing the moon's shape for each evening on a calendar and then determining the pattern in the shapes over several weeks.

Planning Ahead

This lesson involves the observation of daytime and nighttime sky. It is important to remind students of the danger of looking directly at the sun.

Motivation

Do a brainstorming activity with students using a prompt like: "Words that come to mind when I think of the sky." You can choose to have students write these words individually, or you can record the group's thoughts at the front of the room, or students can simply call out the words with no recording.

Development

Have students go outside to observe the daytime sky, reminding them of the danger of looking directly at the sun. You can take advantage of the opportunity to discuss the importance of detailed observations, and continue to encourage these once back inside.

  • What objects do you see?
  • Are any of these objects moving? Describe how they are moving.
  • Which of these objects do you think you would be able to see at night?

Have students create a journal page, documenting their observations in words and pictures. The Science NetLinks student sheet Daytime Sky is available for this purpose. Allow students ample time to share their illustrations, or bind them into a class book to read aloud and leave in the classroom library. Lead students in a discussion of how they think the sky's objects will change over time.

  • What do you think will still be in the sky tonight?
  • What do you think will still be in the sky tomorrow?

Have students complete a follow-up activity at home, this time documenting objects in the evening or nighttime sky. Again, have students complete a journal entry based on their observations. You may wish to have students use the Science NetLinks student sheet Nighttime Sky. Allow students ample time to discuss their findings, noting differences due to times at which they observed the sky. Discuss which objects were seen in both the daytime and nighttime sky. This could be repeated for several days, encouraging students to realize constancy and change. For example, take the students outside at different times, in different conditions, etc. Have students draw pictures of objects overhead relative to objects on the ground.

Assessment

In order to summarize Objects in the Sky, as well as make the distinction between daytime and nighttime objects, have students complete the Science NetLinks assessment sheet What Objects Do You See in the Sky? Here, students are asked to draw, and if appropriate, label objects that might be seen in the daytime or nighttime sky. Also, students can revisit the list generated in the Motivation exercise and modify the words that come to mind when they think of the sky. They can include the names of various objects in the sky, as well as some descriptive characteristics.


How to identify satellites that I see at night?

Bit of context, my dog is getting older and can't really "hold it in" all night now so I've started taking him out at around 12-1am every night. I live in a rural area in the UK and so get some good dark skies.

When the skies are clear I can't help but look up and I see many, many satellites of varying colours. Most I've seen go East-West, I've seen some polar going South-North and even some West-East (which I honestly didn't know was a thing).

It's become something of a hobby, seeing how many I can spot over the 30-45 minutes I'm out and usually I see 2-5 and it's rare I see none. I saw the starlink train on one occasion and that just put me in a state of awe.

My question is, is there a way I can identify which satellites I'm seeing? Like I write down what time I saw them, and then cross reference when I get back to identify them? Iɽ love to be able to keep a log and tally on which ones I see and how frequently.

This is probably a strange question for this sub and might be off topic, but there's just something about it I find so mystical, these are things that we've built that are in the cold emptiness of space, silently moving overhead and overlooked by most. If anyone could help, even if it's a no, then thank you in advance :)

There’s an app call « Satellite Tracker » that will give you the paths and names and location of various satellites and the exact time they’ll be visible (using your localization).

I strongly recommend Star Walk 2. It is interactive while you move your phone around and gives you position of the sun, moon, earth axis, stars, galaxies, etc. It is amazing really. Extremely well done !

I always keep those app open while out in the backcountry because I know I want to know where which planet is and just look up and see Jupiter, Mars, etc. It is a cool feeling !

Oh wow I've had the free version (as in no paid extras) of Star Walk 2 for a while now and only after reading your comment did I actually check what extras you could get for it, had no idea they have a satellite one for £0.99. Can't believe I've had it all this time haha

Found it tricky to use while walking him but might make some dedicated trips out. Cheers mate!

Nah I haven't but just Googled it, looks decent might give it a go

There is also an Android app.

I use Heavens Above for this purposes, it's very good. Surprised it didn't get mentioned earlier but go figure.

Lists all satellite overpasses for the next few days, and allows you to see them pass overhead on a sky map.

A real short answer: Without a lot of effort, it's not easy to write them down and identify them later.

More details: There's a lot of satellites up there, so there's a lot to try and track down. But it's certainly not impossible, there's lots of organizations like this one (https://maps.esri.com/rc/sat2/index.html) that track pretty much anything that's up there and is either published (commercial satillites, NASA, etc.) or not but visible to a telescope (and therefore our naked eyes), which is how we roughly know what spy satellites there are, and where they are (but not what they do). The good news is that if you can see it, its bright, which means its big, and that pretty much rules out cube sats, unless it's particularly shiny or you happened to see it just when the solar panels are reflecting off of it. So if you can make good notes of where it was and where it was heading, you might be able to track it down by looking through big/bright satellites. The difficulty is that youɽ need a good idea of where it was to a few degrees, and its direction, to back that up to when you saw it from the current position on the map, or go look through ephemeris data and back calculate it, which would be a lot of effort.

More realistically is to quickly check with a current map like that above, or use a augmented reality app like Star Walk that includes position data for major satellites and can help you identify it if you point your phone at it (I haven't played much with that feature but am pretty pleased with its normal star spotting abilities).

I can speak more to what you're seeing in the types of satellites. The East-West are the most common because they are easiest to launch, and could be most things, but include communications, Earth Science, the ISS, and Starlink as you mentioned (at various inclinations). The polar orbits are going to mostly be Earth observation satellites for anything ranging from Earth science to meteorology to planet labs mapping the Earth every few days. They use polar orbits because you can either be sun synchronous (see the same spot at the same time of day every pass) or let the Earth rotate under them and see the whole Earth in a few days, both of which are great for observations, but are more expensive orbits to get into for delta-V costs, so usually aren't used unless you need one of those features.


Identify moving object in the sky at night? - Astronomy

My friends and I saw an object that looked like a star moving across the sky. All of a sudden it got very bright and seemed to explode. What was I seeing? Was it a supernova?

Unfortunately what you saw wasn't a supernova explosion! Supernovae visible to the unaided eye have happened only rarely in history, and wouldn't appear to come from a moving star. What you saw in the sky was a satellite. Satellites in orbit look like stars, but they move across the sky, and there are a lot of them visible on any given night. You can see the satellites because sunlight reflects off of their solar panels or communications antennas, and sometimes they will appear to "flare" briefly as sunlight glints off of something on the spacecraft. The global set of Iridium satellites produce especially bright flares that can be the brightest thing in the sky! A good place to find out when satellites are supposed to be visible at your location is Heavens-Above.


Military Eyewitness Captures 'Transparent UFO' On Night Vision

A "low, slow, silent, see-through triangle" was videotaped in the sky above Leland, North Carolina, on the night of May 13, 2014.

The man who taped the event -- an alleged military combat instructor who prefers to remain anonymous -- reported it in August to MUFON, the Mutual UFO Network, where it's listed as case #58923 and is still under investigation.

Here is part of the witness description as reported to MUFON:

I was looking through [night vision] goggles and noticed a 'plane' coming toward me from the north, heading south. It was relatively low, 5,000 feet or a little less. I'm pretty good at estimating distances, I'm an experienced skydiver and long-distance shooter. I thought it was a little weird that I wasn't hearing it coming toward me, so I started recording on the PVS-14 [night vision monocular].

As I'm watching it, I notice that as it's passing stars, I could see stars through the craft! I saw stars through the 'fuselage' of the craft! Later, I confirmed this when I reviewed the video.

Watch the object in night vision here. The witness description continues below.

The craft was in the shape of a triangle. There were two lights at the rear of the vehicle, circular, with a blinking light, also circular, almost between them, just a little above the two rear lights. The light in front was shaped like a triangle itself, with a small, round light right behind it. So all together: five lights. This thing was low and slow and silent!!

The last weird thing that I noticed was that, when I took the goggles down for a second to get a bearing as to where it was in the sky, I couldn't see any of the lights, not the fixed lights, not the single blinking light. I couldn't see it without night vision goggles.

So, what, exactly, are we to make of all of this?

"What struck me was that I have seen this before. This is very likely none other than an aerial refueling operation at night," MUFON chief photo and video analyst Marc Dantonio told Open Minds TV.

"I have seen this exact same thing flying right over my house at night," Dantonio said. "What surprises many people is that large aircraft also aerially refuel as well as fighters and this is even more odd-looking. If you notice in the video in this case, the aircraft following behind is a regular full size jet aircraft showing normal navigation lighting, and the forward aircraft has its lighting on as well, minus strobes, which is probably an anti-glare procedure of some sort for the aft pilot so he can maneuver to the fueling boom."

In the following composite image, a star can be seen moving through what could be mistaken for the fuselage of the aerial object, if it's a single aircraft. The red arrows show the position of the star as the object moves in the sky.

What would account for the video appearing to show some stars moving through the aircraft fuselage, or the fact that the witness didn't hear any sound during his sighting?

"As far as sound, these two jets were much higher up than [the witness] thought, and this explains the lack of sound," said Dantonio. And as far as the stars passing 'through' the aircraft, they can clearly be seen passing between them, but if you end up thinking that this is one large object, then one might think you are seeing stars passing through a transparent, larger object."

To get some further opinion on this case, HuffPost reached out to Ben Hansen, president of NightVisionOps.com.

"[Marc and I] agree that it looks as if the object was filmed 'in-camera.' What's being alleged as stars do appear consistent with what stars look like," Hansen told HuffPost.

Hansen didn't agree with Dantonio's idea that the video shows a refueling operation, because it appears that the objects turn approximately 180 degrees during the course of the video.

"I spoke with a guy who was in the Air Force with advanced degrees in aeronautical science, and after showing him the video, he said you have 30 seconds to connect a plane that's being refueled to the refueler, and protocol is to maintain straight and level flight while you're refueling. Both he and I agree that it makes no sense, and would probably be impossible for this to be any type of plane that's refueling while doing a turn," Hansen said.

According to Dantonio, while the video appears to show the craft (or more than one craft) turning in the sky, he believes this is the result of the videographer actually turning the camera on his tripod, to keep the objects in view. In that scenario, Hansen would be correct in saying that the aircraft were most likely going in a straight line during a refueling operation. He also shared his own similar encounter with a flying triangle.

"In May of 2013, I witnessed a triangular craft in California which, I believe -- if I would've had my night vision -- it would've looked very similar to what [this North Carolina eyewitness] filmed. The underside of the triangle looked exactly like the sky above in color. I didn't see stars through it, but I have an open mind that some form of cloaking technology may already exist.

"Even if it's not ours," Hansen added, "if this is a full-scale craft and not some type of a remote controlled model, this exhibits unconventional maneuvering and cloaking capability that's quite extraordinary."

"With the Star Walk app, if you hold your iPod up towards the sky, you can see all the stars and constellations. It even tells you the names of all the planets. Then, if you point it towards the ground, it shows you what all the stars are in the other hemisphere. It’s brilliant, and if you’re ever somewhere with a clear sky and no light pollution, it’s a revelation. It’s beautifully designed and makes clever use of the available technology. I’m fascinated by astronomy, but even if you’re not, give this a go."

"It’s jam-packed with imagery and data on the 200,000 stars and planets in its database, and has a calendar so you can keep track of interesting celestial events. I particularly like the beautiful imagery it uses to show constellations and detail on the planets."
