A Lot of Galaxies Need Guarding in This NASA Hubble View
May 05, 2017 (SPX)
A stunning example is a galaxy cluster called Abell 370 that contains an astounding assortment of several hundred galaxies tied together by the mutual pull of g...
Vista Peeks Through The Small Magellanic Cloud's Dusty Veil
May 04, 2017 (SPX)
VISTA's infrared capabilities have now allowed astronomers to see the myriad of stars in this neighbouring galaxy much more clearly than ever before. The result...
Four Questions: A Ride On NASA's Eye in the Sky
May 04, 2017 (SPX)
Q: What is your motivation to study planetary systems like Epsilon Eridani? A: Epsilon Eridani is the closest star that hosts a debris disk. Therefore, many con...
Hubble's bright shining lizard star
May 03, 2017 (SPX)
Despite being remarkable in its own right - it has bright bursts of star formation and recorded supernova explosions - it blends into the background somewhat th...
Origin of Milky Way's Hypothetical Dark Signal May Not Be So Dark
May 03, 2017 (SPX)
"Our study shows that we don't need dark matter to understand the gamma-ray emissions of our galaxy," said Mattia Di Mauro from the Kavli Institute for Particle...
Is Dark Matter Fuzzy
May 03, 2017 (SPX)
For several decades, astronomers have known about dark matter. Although it cannot be observed directly, dark matter does interact via gravity with normal, radia...
Astrophysicists discovered a star polluted by calcium
May 02, 2017 (SPX)
In particular, it was found that the calcium abundance in the stellar atmosphere exceeds the solar one by a factor of six, which hints at the possibility that t...
NASA's Webb Telescope Completes Goddard Testing, Heading to Texas for More
May 02, 2017 (SPX)

UCI physicists design 2-D materials that conduct electricity at almost the speed of light
Apr 27, 2017 (SPX)
In three separate studies appearing this month in Nature, Science Advances and Nature Materials, UCI researchers and colleagues from UC Berkeley, Lawrence Berke...
Astrophysicists studied the 'rejuvenating' pulsar in a neighboring galaxy
Apr 27, 2017 (SPX)
Massive young stars die, exploding as bright supernovae. In this process, their outer layers of material are thrown off, and the core shrinks, usually becoming ...
James Webb Space Telescope Mirror Seen in Full Bloom
Apr 27, 2017 (SPX)
Once launched into space, the Webb telescope's 18-segmented gold mirror is specially designed to capture infrared light from the first galaxies that formed in t...

Apr 25, 2017 (SPX)
Now, for the first time, a team of NASA scientists has analyzed dozens of TGFs launched by the largest and strongest weather systems on the planet: tropical sto...
NASA's Cassini, Voyager missions suggest new picture of sun's interaction with galaxy
Apr 25, 2017 (SPX)
The sun releases a constant outflow of magnetic solar material - called the solar wind - that fills the inner solar system, reaching far past the orbit of Neptu...
Keck captures rare high-resolution images of exploded star
Apr 24, 2017 (SPX)
