The Aug. 21, 2017, total solar eclipse was rare in its long, uninterrupted path over land, which provided scientists with a rare chance to investigate the Sun and its influence on Earth in ways that aren’t usually possible. On Dec. 11, researchers discussed initial findings based on observations gathered during the eclipse. via NASA http://ift.tt/2AszyKt
Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds -- mostly. On the third night of returning to same peaks, though, the sky not only cleared up but lit up with a spectacular auroral display. Arms went high in the air, patience and experience paid off, and the creative featured image was captured as a composite from three separate exposures. The setting is a summit of the Austnesfjorden fjord close to the town of Svolvear on the Lofoten islands in northern Norway. The time was early 2014. Although our Sun is nearing Solar Minimum and hence showing relatively little surface activity, holes in the upper corona have provided some nice auroral displays over the last few months. via NASA http://ift.tt/2nI8JvT
This composition in stardust covers over 8 degrees on the northern sky. The mosaicked field of view is west of the familiar Pleiades star cluster, toward the zodiacal constellation Aries and the plane of our Milky Way Galaxy. At right in the deep skyscape is bluish Epsilon Arietis, a star visible to the naked-eye and about 330 light-years away. Reflecting starlight in the region, dusty nebulae LBN762, LBN753, and LBN743 sprawl left to right across the field, but are likely some 1,000 light-years away. At that estimated distance, the cosmic canvas is over 140 light-years across. Near the edge of a large molecular cloud, their dark interiors can hide newly formed stars and young stellar objects or protostars from prying optical telescopes. Collapsing due to self-gravity, the protostars form around dense cores embedded in the molecular cloud. via NASA http://ift.tt/2A1Zfx4
December's Full Moon phase occurred near perigee, the closest point in its orbit around our fair planet. Big and bright, the fully illuminated lunar disk sets over rugged mountains in this early morningscape from Turin, Italy. Captured just before sunrise on the opposite horizon, scattered sunlight near the edge of Earth's shadow provides the beautiful reddish glow of the alpine peaks. Hills in the foreground are still in shadow. But the scattered sunlight just illuminates the dome and towers of Turin's historic Basilica of Superga on a hilltop near the lower right in the telephoto frame. via NASA http://ift.tt/2BGwGG3

As seen from planet Earth, all the lunar and solar eclipses of 2017 are represented at the same scale in these four panels. The year's celestial shadow play was followed through four different countries by one adventurous eclipse chaser. To kick off the eclipse season, at top left February's Full Moon was captured from the Czech Republic. Its subtle shading, a penumbral lunar eclipse, is due to Earth's lighter outer shadow. Later that month the New Moon at top right was surrounded by a ring of fire, recorded on film from Argentina near the midpoint of striking annular solar eclipse. The August eclipse pairing below finds the Earth's dark umbral shadow in a partial eclipse from Germany at left, and the vibrant solar corona surrounding a totally eclipsed Sun from the western USA. If you're keeping score, the Saros numbers (eclipse cycles) for all the 2017 eclipses are at bottom left in each panel. via NASA http://ift.tt/2AAbJ0j

To some, it may look like a beehive harboring an evil bee. In reality, the featured Hubble image captures a cosmic pillar of dust, two-light years long, inside of which is Herbig-Haro 666 -- a young star emitting powerful jets. The structure lies within one of our galaxy's largest star forming regions, the Carina Nebula, shining in southern skies at a distance of about 7,500 light-years. The pillar's layered outline are shaped by the winds and radiation of Carina's young, hot, massive stars, some of which are still forming inside the nebula. A dust-penetrating view in infrared light better shows the two, narrow, energetic jets blasting outward from a still hidden infant star. via NASA http://ift.tt/2Bzxqww
Frigid air blowing from Eastern Russia created dramatic cloud formations over the Sea of Okhotsk in late November, 2017.

What's happening on the horizon? The horizon itself, past a spinach field in Guatemala, shows not only trees but a large volcano: the Volcán de Fuego (Volcano of Fire). The red glow at the top of the volcano is hot lava. But your eye may also be drawn to the blue circle above the horizon on the left. This circle surrounds the Moon and, together with other colors, is called a corona. A corona is caused by diffraction of light -- here moonlight -- by small water droplets in the Earth's intervening atmosphere. A break in the clouds on the right shows stars and even the planet Saturn far beyond the volcano. Although Volcán de Fuego frequently undergoes low-level activity, the astrophotographer considered himself lucky to capture the scene just during an explosive eruption in late September. via NASA http://ift.tt/2klfuTd

Fans of our fair planet might recognize the outlines of these cosmic clouds. On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name North America Nebula to the emission region cataloged as NGC 7000. To the right, just off the North America Nebula's east coast, is IC 5070, whose profile suggests the Pelican Nebula. The two bright nebulae are about 1,500 light-years away, part of the same large and complex star forming region, almost as nearby as the better-known Orion Nebula. At that distance, the 6 degree wide field of view would span 150 light-years. This careful cosmic portrait uses narrow band images to highlight the bright ionization fronts and the characteristic red glow from atomic hydrogen gas. These nebulae can be seen with binoculars from a dark location. Look northeast of bright star Deneb in the constellation of Cygnus the Swan. via NASA http://ift.tt/2jysEbh

The small, northern constellation Triangulum harbors this magnificent face-on spiral galaxy, M33. Its popular names include the Pinwheel Galaxy or just the Triangulum Galaxy. M33 is over 50,000 light-years in diameter, third largest in the Local Group of galaxies after the Andromeda Galaxy (M31), and our own Milky Way. About 3 million light-years from the Milky Way, M33 is itself thought to be a satellite of the Andromeda Galaxy and astronomers in these two galaxies would likely have spectacular views of each other's grand spiral star systems. As for the view from planet Earth, this sharp composite image nicely shows off M33's blue star clusters and pinkish star forming regions along the galaxy's loosely wound spiral arms. In fact, the cavernous NGC 604 is the brightest star forming region, seen here at about the 7 o'clock position from the galaxy center. Like M31, M33's population of well-measured variable stars have helped make this nearby spiral a cosmic yardstick for establishing the distance scale of the Universe. via NASA http://ift.tt/2zzRm20
Few astronomical sights excite the imagination like the nearby stellar nursery known as the Orion Nebula. The Nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud. Many of the filamentary structures visible in the featured image are actually shock waves - fronts where fast moving material encounters slow moving gas. The Orion Nebula spans about 40 light years and is located about 1500 light years away in the same spiral arm of our Galaxy as the Sun. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion. The featured image, taken last month, shows a two-hour exposure of the nebula in three colors. The whole Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years. via NASA http://ift.tt/2ibgKYp
Follow this vertical panoramic view from horizon to horizon and your gaze will sweep through the zenith of a dark night sky over Pic du Midi mountaintop observatory. To make the journey above a sea of clouds, 19 single exposures were taken near the end of night on October 31 and assembled in a mercator projection that renders the two horizons flat. Begin at the top and you're looking east toward the upsidedown dome of the observatory's 1 meter telescope. It's easy to follow the plane of our Milky Way galaxy as it appears to emerge from the dome and angle down toward the far horizon. Just to its right, the sky holds a remarkable diffuse glow of zodiacal light along our Solar System's ecliptic plane. Zodiacal light and Milky Way with star clusters, cosmic dust clouds and faint nebulae, cross near the zenith. Both continue down toward the airglow in the west. They disappear near the western horizon at the bottom, beyond more Pic du Midi observatory domes and a tall communications relay antenna. via NASA http://ift.tt/2iNjjwX

Alnitak, Alnilam, and Mintaka, are the bright bluish stars from east to west (lower right to upper left) along the diagonal in this cosmic vista. Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie from 800 to 1,500 light-years away, born of Orion's well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have some surprisingly familiar shapes, including the dark Horsehead Nebula and Flame Nebula near Alnitak at the lower right. The famous Orion Nebula itself is off the right edge of this colorful starfield. This well-framed, 2-panel telescopic mosaic spans about 4 degrees on the sky. via NASA http://ift.tt/2A3km2Q
Nothing like it has ever been seen before. The unusual space rock 'Oumuamua is so intriguing mainly because it is the first asteroid ever detected from outside our Solar System -- although likely many more are to follow given modern computer-driven sky monitoring. Therefore humanity's telescopes -- of nearly every variety -- have put 'Oumuamua into their observing schedule to help better understand this unusual interstellar visitor. Pictured is an artist's illustration of what 'Oumuamua might look like up close. 'Oumuamua is also intriguing, however, because it has unexpected parallels to Rama, a famous fictional interstellar spaceship created by the late science fiction writer Arthur C. Clarke. Like Rama, 'Oumuamua is unusually elongated, should be made of strong material to avoid breaking apart, is only passing through our Solar System, and passed unusually close to the Sun for something gravitationally unbound. Unlike a visiting spaceship, though, 'Oumuamua's trajectory, speed, color, and even probability of detection are consistent with it forming naturally around a normal star many millions of years ago, being expelled after gravitationally encountering a normal planet, and subsequently orbiting in our Galaxy alone. Even given 'Oumuamua's likely conventional origin, perhaps humanity can hold hope that one day we will have the technology to engineer 'Oumuamua -- or another Solar System interloper -- into an interstellar Rama of our own. via NASA http://ift.tt/2jLMtjj
Yes, but have you ever taken a selfie on Mars? The Curiosity rover on Mars has. This selfie was compiled from many smaller images -- which is why the mechanical arm holding the camera is not visible. (Although its shadow is!) Taken in mid-2015, the featured image shows not only the adventurous rover, but dark layered rocks, the light colored peak of Mount Sharp, and the rusting red sand that pervades Mars. If you look closely, you can even see that a small rock is stuck into one of Curiosity's aging wheels.

Young stars themselves are clearing out their nursery in NGC 7822. Within the nebula, bright edges and complex dust sculptures dominate this detailed skyscape taken in infrared light by NASA's Wide Field Infrared Survey Explorer (WISE) satellite. NGC 7822 lies at the edge of a giant molecular cloud toward the northern constellation Cepheus, a glowing star forming region that lies about 3,000 light-years away. The atomic emission of light by the nebula's gas is powered by energetic radiation from the hot stars, whose powerful winds and light also sculpt and erode the denser pillar shapes. Stars could still be forming inside the pillars by gravitational collapse, but as the pillars are eroded away, any forming stars will ultimately be cut off from their reservoir of star stuff. This field spans around 40 light-years at the estimated distance of NGC 7822. via NASA http://ift.tt/2yWIbIj

Would it be possible to be unable to see stars from a planet somewhere in the Milky Way? - Tina (London, UK)
This is a very good question actually, and a hard one to answer quickly in short for most places in the milky way no - for some extreme cases maybe you could see very few stars (or maybe none). It depends on quite a lot of things, for instance, what you consider a "star". There are many things we can see in the night sky that one might see from Earth or indeed another planet. I'll run through the list of objects and then try to see where in the Milky way we can be to possibly not see them. Below when I say "planetary system" I mean the solar system for your planet.
Other planets in the planetary system (but not all of them):
From Earth we can see Mercury, Venus, Mars, Jupiter and Saturn quite easily, so if your "planetary system" had other planets they may be visible in the night sky from your planets (depending on the brightness of the "planetary systems" star and on where the other planets were compared to your planet. You would also see a moon if your planet had one if it were large enough (some moons cannot be seen). Planets don't look exactly like "stars" as they wander across the sky due to your planets motion and the other planets motion (however if you are far enough away from your sun this motion would be very small and they could basically look like bright stars - but your planet would probably be very very cold for this to be true).
- Asteroids comets meteors (think shooting stars) - even if there are no other planets in your "planetary" systems an observer would be able to see comets and asteroids like we do on Earth if your planet was close enough to its sun - but these don't really look like "normal" stars and wouldn't be seen every night and move a lot
- Stars - most of the sky you see in the sky are stars that are pretty close by, the brightest ones could be either the ones that are the closest or the ones that are the most massive so from looking it is quite hard to tell how far away stars that you can see, some of the most massive stars can be a few thousand light years away (As in this article here) but the milky way is huge (100,000 light years across) so we definitely cannot see all the stars in the milky way (as individual "points" in the sky) even with a powerful telescope.
The Milky way itself - on a clear night (maybe not in areas with light pollution like most of the UK these days) you can see a faint "haze" running across the sky this is the milky way itself (looking towards the center) it is absolutely huge (the milky way is a disk with a bulge at the center and we are in that disk) - the center is too far away to see individual stars but we see the combined light from many of the stars and the lighting of gas and dust by those stars. With a telescope or good camera it looks like this:
Nebulae and Galaxies - as well as "the whole milky way" depending where you are in the galaxy you may be able to see areas of dust and gas (eliminated by the stars) from Earth you need a telescope to really see these but they are there, the same is true for galaxies (other milky ways) of which a few can be seen with only your eyes (Andromeda in the northern hemisphere) and some small galaxies that orbit our own milky way - these mostly look like blobs in the sky but could be mistaken for stars.
So now to try to answer your question, is there anywhere in the milky way we could go (i.e. where you could put a planet) where we wouldn't see any "stars".
- For other planets - this is easy - if your planetary system had no other planets or they were really close to "your sun" or really far away from "your sun" you might not see them.
- For asteroids etc - chances are if you have a planet in your planetary system (that you are standing on) you will probably have asteroids and comets but seeing these events could be very rare - Halley's comet, for example, may be seen once every 75 years.. so these certainty wouldn't be "normal" "stars".
- For stars - This is a hard one, as I said above we can only see stars that are pretty close to the sun from Earth (even the massive ones we see, which are the most distant are pretty close compared to the size of the galaxy). The way to imagine this is that we see a small "bubble" of our milky way as individual stars and the rest form the "haze" of the milky way. The galaxy itself it a spiral galaxy (looks like this: https://www.universetoday.com/.../Milky-Way-artist-ESO...) so you could imagine areas in the galaxy where a planet would see fewer stars than we see on Earth or more stars than we see on Earth - and actually the more towards the center you go the more stars you can see (on average) so being near the edge of the milky way would definitely let you see fewer stars. There may be some areas on the very outskirts of the milky way that you could see very few stars.
- For the Milky Way - It would be very hard to be somewhere where you cannot see the milky way unless you were very far away from its center (the sun is 30,000 light years from the center) so with a diameter of 100,000 light years (radius of 50,000 light years) you could only go about 1.5 times as far from the center as we are before you reach the "edge" of the milky way... so you would still see** "something" of the milky way from your planet (as we can see the Andromeda galaxy that is about 2.5 MILLION light years away (albeit VERY faintly) you would have to be very far away to not see the milky way at all!)
- For other galaxies - If you were in the milky way you would always** be able to see galaxy such as Andromeda from the milky way
Being in a very dusty/gas-rich part of the milky way: dust basically blocks light, when you look at the milky way those dark areas in the middle do have stars there is just lots of gas and dust in the way, enough to block out the light from the stars behind - I'm not sure how possible it would be to find an area in the milky way with enough dust between you and all other stars that you see no stars though, but it is possible (you would have to combine being very dusty with being far enough away from other bright stars) - this occurs in areas in the milky way where stars are being born, or even if your planet was very young you may have enough dust in your own solar system to block out the light from other stars
- If you were on a planet that was "tidally locked" (this means one side faces its sun at all times) and you only lived on the day side and couldn't/didn't travel to the night side you may not see any stars (but it would also never be night time) - it would probably also be unpleasantly warm unless you were far enough away from the star but then it is difficult to make a planet "tidally locked".
Light pollution or thick atmosphere (cloudy atmosphere) - if there was significant light pollution on your planet (i.e. like living in the centre of a city) you may not see any stars at all and just a "haze" from all the light pollution around! Equally if you had a thicker atmosphere it could almost seem like it was cloudy all the time or maybe your planet could be cloudy the whole time (but the planet might then not be very habitable and who wants to live on a planet with 100% cloud cover all the time) - you'd still get day and night but never see the star unless you went up into space/away from all the light pollution. Also, light pollution could occur naturally certain chemistry and biology can produce fluorescence in the atmosphere that could block out any light from stars.
The Tarantula Nebula is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud, about 180 thousand light-years away. The largest, most violent star forming region known in the whole Local Group of galaxies, the cosmic arachnid sprawls across this spectacular view composed with narrowband data centered on emission from ionized hydrogen and oxygen atoms. Within the Tarantula (NGC 2070), intense radiation, stellar winds and supernova shocks from the central young cluster of massive stars, cataloged as R136, energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star forming regions with young star clusters, filaments, and blown-out bubble-shaped clouds. In fact, the frame includes the site of the closest supernova in modern times, SN 1987A, right of center. The rich field of view spans about 1 degree or 2 full moons, in the southern constellation Dorado. But were the Tarantula Nebula closer, say 1,500 light-years distant like the local star forming Orion Nebula, it would take up half the sky. via NASA http://ift.tt/2AJQWqN
Found among the rich starfields of the Milky Way, star cluster NGC 7789 lies about 8,000 light-years away toward the constellation Cassiopeia. A late 18th century deep sky discovery of astronomer Caroline Lucretia Herschel, the cluster is also known as Caroline's Rose. Its flowery visual appearance in small telescopes is created by the cluster's nestled complex of stars and voids. Now estimated to be 1.6 billion years young, the galactic or open cluster of stars also shows its age. All the stars in the cluster were likely born at the same time, but the brighter and more massive ones have more rapidly exhausted the hydrogen fuel in their cores. These have evolved from main sequence stars like the Sun into the many red giant stars shown with a yellowish cast in this lovely color composite. Using measured color and brightness, astronomers can model the mass and hence the age of the cluster stars just starting to "turn off" the main sequence and become red giants. Over 50 light-years across, Caroline's Rose spans about half a degree (the angular size of the Moon) near the center of the wide-field telescopic image. via NASA http://ift.tt/2zzTXMu
The well-known Pleiades star cluster is slowly destroying part of a passing cloud of gas and dust. The Pleiades is the brightest open cluster of stars on Earth's sky and can be seen from almost any northerly location with the unaided eye. The passing young dust cloud is thought to be part of Gould's Belt, an unusual ring of young star formation surrounding the Sun in the local Milky Way Galaxy. Over the past 100,000 years, part of Gould's Belt is by chance moving right through the older Pleiades and is causing a strong reaction between stars and dust. Pressure from the stars' light significantly repels the dust in the surrounding blue reflection nebula, with smaller dust particles being repelled more strongly. A short-term result is that parts of the dust cloud have become filamentary and stratified. The featured deep image also captured Comet C/2015 ER61 (PanSTARRS) on the lower left. via NASA http://ift.tt/2iPV9kg
Why is Comet Maccholz so depleted of carbon-containing chemicals? Comet 96P/Machholz's original fame derives from its getting closer to the Sun than any other short period comet -- half as close as Mercury -- and doing so every five years. To better understand this unusual comet, NASA's Sun-monitoring SOHO spacecraft tracked the comet during its latest approach to the Sun in October. The featured image composite shows the tail-enhanced comet swooping past the Sun. The Sun's bright surface is hidden from view behind a dark occulter, although parts of the Sun's extended corona are visible. Neighboring stars dot the background. One hypothesis holds that these close solar approaches somehow cause Comet Machholz to shed its carbon, while another hypothesis posits that the comet formed with this composition far away -- possibly even in another star system. via NASA http://ift.tt/2iOfVAW

Sometimes, the sky may seem to smile over much of planet Earth. On this day in 2008, visible the world over, was an unusual superposition of our Moon and the planets Venus and Jupiter. Pictures taken at the right time show a crescent Moon that appears to be a smile when paired with the planetary conjunction of seemingly nearby Jupiter and Venus. Pictured here is the scene as it appeared from Mt. Wilson Observatory overlooking Los Angeles, California, USA after sunset on 2008 November 30. Highest in the sky and farthest in the distance is the planet Jupiter. Significantly closer and visible to Jupiter's lower left is Venus, appearing through Earth's atmospheric clouds as unusually blue. On the far right, above the horizon, is our Moon, in a waxing crescent phase. Thin clouds illuminated by the Moon appear unusually orange. Sprawling across the bottom of the image are the hills of Los Angeles, many covered by a thin haze, while LA skyscrapers are visible on the far left. Hours after the taking of this image, the Moon approached the distant duo, briefly eclipsed Venus, and then moved on. This week, another conjunction of Venus and Jupiter is occurring and is visible to much of planet Earth to the east just before sunrise. via NASA http://ift.tt/2yQsEy2
