The Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth that is stuffing itself with smaller galaxies caught like flies in a web of gravity. The galaxy is so far away that astronomers are seeing it as it looked in the early formative years of the Universe, only 2 billion years after the Big Bang. picked by 2manyusernames 2 years ago

Newborn stars shine like celestial sparklers in a new portrait of the nearby Triangulum Galaxy – the most detailed ultraviolet image of a galaxy ever taken. Astronomers will use the image, taken by NASA's Swift telescope, to create an "age map" of the galaxy's components to understand how galaxies evolve over time. picked by AutumnLotus 8 months ago

Through some of the very first scientific observations with the brand-new Large Binocular Telescope (LBT) in Arizona, astronomers has found that a recently discovered tiny companion galaxy to our Milky Way, named the Hercules Dwarf Galaxy, has truly exceptional properties: while basically all of its known peers in the realm of these tiny dwarf galaxies are rather round, this galaxy at a distance o... read full post picked by AutumnLotus 1 year ago

Orphaned stars are being born in a vast tail of material stretching behind a faraway galaxy. The finding is evidence that orphaned stars — those not orbiting the center of a galaxy in normal fashion — are much more common than thought. picked by AutumnLotus 1 year ago

A newly discovered dwarf galaxy in the Local Group has been found to have formed in a region of space far from our own and is falling into our system for the first time in its history. picked by AutumnLotus 1 year ago

A large galaxy could be lurking unseen in our own cosmic backyard, a pair of researchers says. Such a massive object could explain a mysterious gravitational pull on the Milky Way. picked by AutumnLotus 10 months ago

What do you call an absence of darkness? Dark matter is supposed to be spread throughout the universe, but a new study reports a spiral galaxy that seems to be empty of the stuff, and astrophysicists cannot easily explain why. picked by AutumnLotus 8 months ago

What has appeared as a mild-mannered elliptical galaxy in previous studies is revealing its wild side in new images taken with NASA's Hubble Space Telescope. The Hubble photos show shells of stars around a bright quasar, known as MC2 1635+119, which dominates the center of the galaxy. The shells' presence indicates a titanic clash with another galaxy in the relatively recent past. picked by AutumnLotus 12 months ago

Dubbed SDSSJ0737+3216, the just discovered galaxy is 100 times lighter than our own Milky Way and is the smallest galaxy ever identified at that distance. It is about half the size and approximately one-tenth the "weight" of typical small galaxies found closer to Earth. picked by julea 1 year ago

Astronomers have glimpsed what may be the farthest galaxy we've ever seen, providing a picture of a baby galaxy born soon after the beginning of the universe. picked by AutumnLotus 8 months ago

More than 800,000 snapshots from NASA's Spitzer Space Telescope have been stitched together to create a new "coming of age" portrait of stars in our inner Milky Way galaxy. The image depicts an area of sky 120 degrees wide by two degrees tall. High-res zoomable image. picked by AutumnLotus 4 months ago

In the early 1900s, Edwin Hubble made the startling discovery that our Milky Way galaxy is not alone. It is just one of many galaxies, or "island universes," as Hubble dubbed them, swimming in the sea of space. Now, a century later, NASA's Galaxy Evolution Explorer is helping piece together the evolution of these cosmic species. picked by AutumnLotus 11 months ago

A distant galaxy cluster has turned into a giant particle accelerator, spinning electrons over vast distances at high speeds. Scientists discovered this phenomenon by observing highly energetic X-rays emanating from the Ophiuchus cluster of galaxies. picked by AutumnLotus 9 months ago

ESO's Wide Field Imager has captured the intricate swirls of the spiral galaxy Messier 83, a smaller look-alike of our own Milky Way. Shining with the light of billions of stars and the ruby red glow of hydrogen gas, it is a beautiful example of a barred spiral galaxy, whose shape has led to it being nicknamed the Southern Pinwheel. picked by AutumnLotus 1 month ago

A new image from NASA's Galaxy Evolution Explorer shows baby stars sprouting in the backwoods of a galaxy -- a relatively desolate region of space more than 100,000 light-years from the galaxy's bustling center. picked by AutumnLotus 6 months ago

A young star speeding away from the Milky Way is in fact an alien visitor, astronomers have confirmed. The wayward object is one of several rogues that are giving astronomers a glimpse into the volatile nature of our galaxy and others. picked by AutumnLotus 9 months ago

Daniel Simon is an automotive futurist. He's interned with Lamborghini and worked on concept cars for VW. But the auto industry -- indeed, the galaxy -- could not contain his imagination.(techno-gasm) picked by Bornbad 1 month ago

This Chandra X-ray Observatory image shows the debris of a massive star explosion in the Large Magellanic Cloud, a small galaxy about 160,000 light years from Earth. The supernova remnant (SNR) shown here, N132D, is the brightest in the Magellanic clouds, and belongs to a rare class of oxygen-rich remnants. Most of the oxygen that we breathe on Earth is thought to have come from explosions similar... read full post picked by AutumnLotus 7 months ago

Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide – two ingredients that build life-forming amino acids – in a galaxy some 250 million light years away. picked by AutumnLotus 9 months ago

The NASA/ESA Hubble Space Telescope has captured a new image of the galaxy NGC 1132 which is, most likely, a cosmic fossil – the aftermath of an enormous multi-galactic pile-up, where the carnage of collision after collision has built up a brilliant but fuzzy giant elliptical galaxy far outshining typical galaxies. picked by AutumnLotus 8 months ago
