Buried in the heart of a giant
Jul 05, 2015 (SPX)
Discovered from England by the tireless observer Sir William Herschel on 20 November 1784, the bright star cluster NGC 2367 lies about 7000 light-years from Ear...
Using muons from cosmic rays to find fraying infrastructure
Jul 01, 2015 (SPX)
In the United States, electricity comes with the flip of a switch and heat arrives with the push of a button. Behind such convenience lies a massive infrastruct...
Universe's first stars left unique chemical signatures
Jul 01, 2015 (UPI)
Researchers at Lawrence Livermore National Laboratory are on the case of the missing alpha star signatures. Scientist Brian Bucher recently made a breakthrough ...
Seeing a supernova in a new light
Jul 01, 2015 (SPX)
Type Ia supernovae are the "standard candles" astrophysicists use to chart distance in the Universe. But are these dazzling exploding stars truly all the same T...
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...
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...
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...
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 ...
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...
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...
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...
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...
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: ...
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...
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 ...
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...
