Giant galaxy is still growing
Jun 28, 2015 (SPX)
Astronomers expect that galaxies grow by swallowing smaller galaxies. But the evidence is usually not easy to see -- just as the remains of the water thrown fro...
Discovering a New Stage in the Galactic Lifecycle
Jun 28, 2015 (SPX)
On its own, dust seems fairly unremarkable. However, by observing the clouds of gas and dust within a galaxy, astronomers can determine important information ab...
Astronomers explain why a star is so hot right now
Jun 25, 2015 (SPX)
Astronomers have solved a mystery over small, unusually hot blue stars, 10 times hotter than our Sun, that are found in the middle of dense star clusters. The i...
Intense radio emission from tiny binary star calls for stellar model rethink
Jun 25, 2015 (SPX)
A study led by researchers in the Group of Radio Astronomy of the University of Valencia has determined the mass of a tiny binary star thanks to its intense rad...
Neutron star's echoes give astronomers a new measuring stick
Jun 25, 2015 (SPX)
In late 2013, when the neutron star at the heart of one of our galaxy's oddest supernovae gave off a massive burst of X-rays, the resulting echoes - created whe...
Over 800 dark galaxies found in the famous Coma Cluster
Jun 25, 2015 (SPX)
A group of researchers from the Stony Brook University (the State University of New York) and the National Astronomical Observatory of Japan has discovered 854 ...
NASA simulation suggests black holes may make ideal dark matter labs
Jun 25, 2015 (SPX)
A new NASA computer simulation shows that dark matter particles colliding in the extreme gravity of a black hole can produce strong, potentially observable gamm...
Galactic crashes fuel quasars
Jun 22, 2015 (SPX)
When galaxies collide, bright things happen in the universe. Using the Hubble Space Telescope's infrared vision, astronomers have unveiled some of the previousl...
Best observational evidence yet of first-generation stars in the universe
Jun 22, 2015 (SPX)
Astronomers using the European Southern Observatory's Very Large Telescope (VLT) have discovered by far the brightest galaxy yet found in the early universe and...
Magnetic field discovery gives clues to galaxy-formation processes
Jun 22, 2015 (SPX)
Astronomers making a detailed, multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy's main spiral arm. The discove...
Cosmic ray observatory to expand
Jun 17, 2015 (SPX)
Physicists plan a $6.4 million expansion of the $25 million Telescope Array observatory in Utah so they can zero in on a "hotspot" that seems to be a source of ...
Seeing Where Stars Collide
Jun 17, 2015 (SPX)
Scientists have imaged a cluster of stars, heavily obscured by material in our galaxy, where stars are so densely packed that it is likely a rare environment wh...
Lab mimicry opens a window to the deep interiors of stars and planets
Jun 17, 2015 (SPX)
The matter that makes up distant planets and even-more-distant stars exists under extreme pressure and temperature conditions. This matter includes members of a...
Unknown extreme star formation discovered
Jun 17, 2015 (SPX)
NOEMA (Northern Extended Millimeter Array), the most powerful millimetre radio telescope of the Northern Hemisphere, has unveiled its first astronomical image: ...
A celestial butterfly emerges from its dusty cocoon
Jun 14, 2015 (SPX)
Some of the sharpest images ever made with ESO's Very Large Telescope have, for the first time, revealed what appears to be an ageing star giving birth to a but...
Lonely galaxy lost in space
Jun 11, 2015 (SPX)
Most galaxies are clumped together in groups or clusters. A neighboring galaxy is never far away. But this galaxy, known as NGC 6503, has found itself in a lone...
Nearby 'dwarf' galaxy is home to luminous star cluster
Jun 10, 2015 (SPX)
A team of Tel Aviv University and UCLA astronomers have discovered a remarkable cluster of more than a million young stars are forming in a hot, dusty cloud of ...
Most detailed view ever of star formation in the distant universe
Jun 09, 2015 (SPX)
ALMA's Long Baseline Campaign has produced a spectacularly detailed image of a distant galaxy being gravitationally lensed. The image shows a magnified view of ...
Exiled stars explode far from home
Jun 05, 2015 (SPX)
Sharp images obtained by the Hubble Space Telescope confirm that three supernovae discovered several years ago exploded in the dark emptiness of intergalactic s...
Charting the Milky Way From the Inside Out
Jun 04, 2015 (JPL)
Imagine trying to create a map of your house while confined to only the living room. You might peek through the doors into other rooms or look for light spillin...
