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 9 months ago

Supernova will now go by the name Rock Star: Supernova like the show that created the band. Not like the band named Supernova that sued them. picked by musicgirldani 2 years ago

The Gemini South Multi-Object Spectograph (GMOS) recently captured a dramatic image of a vast cloud complex named DEM L316 located in the Large Magellanic Cloud. The peanut-shaped nebula appears to be a single object, but the latest research indicates that it is really comprised of two distinct gas and dust clouds formed by different types of supernova explosions. picked by AutumnLotus 11 months ago

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

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

An explosive star within our galaxy is showing signs of an impending eruption, at least in a cosmic time frame, and has for quite some time. From 1838 to 1858, the star called Eta Carinae brightened to rival the light of Sirius, the brightest star in the sky, and then faded to a dim star. Since 1940 it has been brightening again, and scientists think Eta Carinae will detonate in 10,000 to 20,000 y... read full post picked by AutumnLotus 11 months ago

A colossal cloud of gas is racing toward a collision with our galaxy, and when it hits, the crash could trigger an intense burst of star formation. picked by AutumnLotus 11 months ago

The latest image from the NASA/ESA Hubble Space Telescope reveals a sharp view of the spiral galaxy NGC 2397. This image also shows a rare Hubble view of the early stages of a supernova - SN 2006bc, discovered in March 2006. picked by AutumnLotus 8 months 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 9 months 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 2 years 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

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 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 1 year ago

The shape of the mysterious cloud of antimatter in the central regions of the Milky Way has been revealed by ESA’s orbiting gamma-ray observatory Integral. The unexpectedly lopsided shape is a new clue to the origin of the antimatter. picked by AutumnLotus 11 months ago

Astronomers recently captured a supernova's blinding flash "echoing" off dust 400 light-years from the detonation site in the Large Magellanic Cloud — which means Earthly observers may have seen the original blast 400 years ago. picked by AutumnLotus 8 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 3 months ago

In a distant galaxy, a star orbiting a massive central black hole strays too close to the insatiable giant and is torn apart. But before it can be devoured, the star lets out one last scream in a flare of light that slowly echoes across the galaxy. Astronomers on Earth pick up this faint call and use it to map the nucleus of the galaxy from which it emanated. picked by AutumnLotus 7 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 1 year ago
