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 3 years 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 2 years 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

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 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 2 years 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 2 years 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 1 year 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 2 years 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 year ago

The giant galaxy Messier 87 has finally been sized up, but outer parts that should have been there are missing, scientists now find. The galaxy is smaller than expected. picked by AutumnLotus 6 months 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 2 years ago

Astronomers have identified a type of galaxy that represents a "missing link" in our understanding of the Universe. Spiral and elliptical galaxies used to be known exclusively as "blue" and "red", respectively. But two studies show that one in five galaxies is a red spiral. picked by AutumnLotus 1 year ago

New images show the "last meal" of a giant cannibal galaxy as it gobbles down a smaller spiral galaxy, which has been twisted and warped from being devoured.

The giant galaxy, Centaurus A (NGC 5128) is the nearest giant, elliptical galaxy, at a distance of about 11 million light-years. picked by AutumnLotus 7 hours ago

Australian astronomers have made the most detailed map yet of a radio galaxy, which could lead to a better understanding of these strange phenomena.

The map of Centaurus A, a galaxy in the Centaurus constellation, covers a segment of sky 200 times the area of the full moon. picked by AutumnLotus 5 months ago

Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. To their surprise and delight, the satellite captured similar emissions from dozens of other galaxies. Now its successor, the Fermi Gamma-ray Space Telescope, is filling in the picture with new finds of its own. 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 2 years ago

This new guide for astronomers, known as the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) shows the Milky Way in submillimetre-wavelength light (between infrared light and radio waves). Images of the cosmos at these wavelengths are vital for studying the birthplaces of new stars and the structure of the crowded galactic core. picked by AutumnLotus 5 months ago

Astronomers have argued for years over whether massive galaxies form from scratch, or by chunking together smaller galaxies. Lately, evidence is building for the latter theory, and a new study adds to the growing picture of galaxy formation as a clumpy affair. picked by AutumnLotus 1 year 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 2 years ago
