History of Andromeda Galaxy Studied Through Stellar Remains
Dec 19, 2015 (SPX)
Planetary nebulae, stars similar to the Sun which have burnt up their fuel and ejected their external layers, make it possible to study two main substructures o...
VERITAS detects gamma rays from halfway across the universe
Dec 19, 2015 (SPX)
In April 2015, after traveling for about half the age of the universe, a flood of powerful gamma rays from a distant galaxy slammed into Earth's atmosphere. Tha...
Survey Maps Neutral Hydrogen in Northern Sky
Dec 19, 2015 (SPX)

A new spin on star-forming galaxies
Dec 18, 2015 (SPX)
Australian researchers have discovered why some galaxies are "clumpy" rather than spiral in shape - and it appears low spin is to blame. The finding challenges ...
Supernova explosion caught in the act
Dec 17, 2015 (ESA)
The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calcul...
Quasar outburst revises understanding of universe, quasars
Dec 17, 2015 (SPX)
"On April 20, 2015, we got word from the Fermi satellite and the MAGIC telescope observatory that they had spotted a very active source - one that was getting v...
Gamma rays from distant galaxy tell story of an escape
Dec 16, 2015 (SPX)
A flare of very high-energy gamma rays emitted from a galaxy halfway across the universe has put new bounds on the amount of background light in the universe an...
XXL hunt for galaxy clusters
Dec 16, 2015 (SPX)
Galaxy clusters are massive congregations of galaxies that host huge reservoirs of hot gas - the temperatures are so high that X-rays are produced. These struct...
New Results from the LUX Dark Matter Detector
Dec 15, 2015 (SPX)
The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Bl...
A 'ghost from the past' recalls the infancy of the Milky Way
Dec 11, 2015 (SPX)
When our galaxy was born, around 13,000 million years ago, a plethora of clusters containing millions of stars emerged. But over time, they have been disappeari...
NASA telescopes detect Jupiter-like storm on small star
Dec 11, 2015 (JPL)
Astronomers have discovered what appears to be a tiny star with a giant, cloudy storm, using data from NASA's Spitzer and Kepler space telescopes. The dark stor...
What spawned the Jellyfish Nebula?
Dec 11, 2015 (SPX)
The Jellyfish Nebula, also known by its official name IC 443, is the remnant of a supernova lying 5,000 light years from Earth. New Chandra observations show th...
VLT revisits a curious cosmic collision
Dec 10, 2015 (SPX)
The spectacular aftermath of a 360 million year old cosmic collision is revealed in great detail in new images from ESO's Very Large Telescope at the Paranal Ob...
Alternative stellar lifestyle: Common, curious, solved at last
Dec 09, 2015 (SPX)
Starting around 1950, a series of advances formed a clear and accepted picture of how individual stars are born, evolve and die. As they age, the changing patte...
Scientists explain origin of heavy elements in the Universe
Dec 09, 2015 (SPX)
In a letter published in the prestigious journal Nature Physics, a team of scientists from The Hebrew University of Jerusalem suggests a solution to the Galacti...
Titan helps researchers explore explosive star scenarios
Dec 09, 2015 (SPX)
Exploding stars may seem like an unlikely yardstick for measuring the vast distances of space, but astronomers have been mapping the universe for decades using ...
Radio Shadow Reveals Tenuous Cosmic Gas Cloud
Dec 08, 2015 (SPX)
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered the most tenuous molecular gas ever observed. They detected the absorp...
Texas Astronomer Solves Mystery of 'Born Again' Stars
Dec 08, 2015 (SPX)
University of Texas astronomer Natalie Gosnell has used Hubble Space Telescope to better understand why some stars aren't evolving as predicted. These so-called...
ALMA spots monstrous baby galaxies cradled in dark matter
Dec 07, 2015 (SPX)
Astronomers discovered a nest of monstrous baby galaxies 11.5 billion light-years away using the Atacama Large Millimeter/submillimeter Array (ALMA). The young ...
Student discovers stellar chamaeleon had astronomers fooled for years
Dec 07, 2015 (SPX)
