Measurements on Cl-36 samples refute decay rate on distance between Earth and Sun
Oct 15, 2014 (SPX)
A group of US American scientists had recently published measurement data concerning the radioactive isotope chlorine-36. The measurement values showed fluctuat...
NuSTAR Telescope Discovers Shockingly Bright Dead Star
Oct 11, 2014 (SPX)
Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over...
Dead star shines on
Oct 11, 2014 (SPX)
A supernova is the cataclysmic death of a star, but it seems its remnants shine on. Astronomers have found a pulsating, dead star beaming with the energy of abo...
Dark matter half what we thought
Oct 10, 2014 (SPX)
A new measurement of dark matter in the Milky Way has revealed there is half as much of the mysterious substance as previously thought. Australian astronomers u...
Zeroing in on a source of gamma rays
Oct 09, 2014 (SPX)
Gamma rays are the highest-energy form of radioactive waves known in the universe. However, how they're made and where they come from have been a bit of a myste...
A Warm Dark Matter Search Using XMASS
Oct 08, 2014 (SPX)
The XMASS collaboration, led by Yoichiro Suzuki at the Kavli IPMU, has reported its latest results on the search for warm dark matter. Their results rule out th...
NASA's Swift Mission Observes Mega Flares from a Mini Star
Oct 01, 2014 (SPX)
On April 23, NASA's Swift satellite detected the strongest, hottest, and longest-lasting sequence of stellar flares ever seen from a nearby red dwarf star. The ...
First dark matter results from underground China lab hosting PandaX-I
Oct 01, 2014 (SPX)
Scientists across China and the United States collaborating on the PandaX search for dark matter from an underground lab in southwestern China report results fr...
Simulations Reveal An Unusual Death for Ancient Stars
Sep 30, 2014 (SPX)
Certain primordial stars-those between 55,000 and 56,000 times the mass of our Sun, or solar masses-may have died unusually. In death, these objects-among the U...
NASA's Swift satellite sees small star ejecting 'super flares'
Sep 30, 2014 (UPI)
Astronomers don't normally use canine clichés, but if they did, they might employ one -- it's not the size of the dog in the fight, it's the size of the fight ...
Most stars are born in clusters, some leave 'home'
Sep 26, 2014 (SPX)
New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up....
Most metal-poor star hints at universe's first supernovae
Sep 26, 2014 (SPX)
A team of researchers, led by Miho N. Ishigaki, at the Kavli IPMU, The University of Tokyo, pointed out that the elemental abundance of the most iron-poor star ...
Particle detector finds hints of dark matter in space
Sep 25, 2014 (SPX)
Researchers at MIT's Laboratory for Nuclear Science have released new measurements that promise to shed light on the origin of dark matter. The MIT group leads ...
Infant solar system shows signs of windy weather
Sep 25, 2014 (SPX)
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star,...

Monster galaxies gain weight by eating smaller neighbours
Sep 22, 2014 (SPX)
Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists...
Violent Origins of Disc Galaxies Probed by ALMA
Sep 19, 2014 (SPX)
For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using ...
Neighboring Andromeda Galaxy to eat Milky Way in 5 billion years
Sep 19, 2014 (UPI)
All galaxies grow by pulling in cosmic debris, gas and dust, and are rather efficient at converting it into new stars. But as galaxies age and grow more massive...
Pulse of a Dead Star Powers Intense Gamma Rays
Sep 17, 2014 (SPX)
Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars. When the most massive stars explode as supernovas, they don't fade into the ...
