'Odd couple' binary makes dual gamma-ray flares
(PhysOrg.com) -- In December 2010, a pair of mismatched stars in the southern constellation Crux whisked past each other at a distance closer than Venus orbits the sun. The system possesses a so-far unique ...
Famous supernova reveals clues about crucial cosmic distance markers
(Phys.org) —A new study using data from NASA's Chandra X-ray Observatory points to the origin of a famous supernova. This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class ...
A cosmic holiday ornament, Hubble-style
(Phys.org)—'Tis the season for holiday decorating and tree-trimming. Not to be left out, astronomers using NASA's Hubble Space Telescope have photographed a festive-looking nearby planetary nebula called ...
Breakthrough study models dying stars in a lab
A team of scientists has successfully reproduced conditions in one of the most hostile environments in the galaxy, enabling them to find out more about how atoms behave in these extreme settings.
Capturing a fleeting starburst
On 11 November 2011, astronomers witnessed a distant star erupt in an incredibly powerful explosion. An international research team including Mikio Morii and colleagues from the MAXI Team at the RIKEN Global ...
Chemists discover new type of molecular bond near white dwarf stars
Can life emerge on planets around cooling stars?
(Phys.org)—Astronomers find planets in strange places and wonder if they might support life. One such place would be in orbit around a white or brown dwarf. While neither is a star like the sun, both glow and so could be ...
Physicists create supernova in a jar (w/ Video)
(PhysOrg.com) -- A team of physicists from the University of Toronto and Rutgers University have mimicked the explosion of a supernova in miniature.
Neon lights up exploding stars
(Phys.org)—An international team of nuclear astrophysicists has shed new light on the explosive stellar events known as novae.
How white dwarfs mimic black holes
(Phys.org)—A remarkable observation by astronomers from the University of Southampton has been published in one of the world's foremost astrophysics research journals.
Massive white dwarf in our galaxy may go supernova
Hubble watching ancient orbs
(Phys.org)—This sparkling picture taken by the NASA/ESA Hubble Space Telescope shows the center of globular cluster M 4. The power of Hubble has resolved the cluster into a multitude of glowing orbs, each ...
The white widow model: A new scenario for the birth of Type Ia supernovae
J. Craig Wheeler has studied the exploding stars called supernovae for more than four decades. Now he has a new idea on the identity of the "parents" of one of the most important types of supernovae—the ...
Failed explosions explain most peculiar supernovae
Supercomputer simulations have revealed that a type of oddly dim, exploding star is probably a class of duds—one that could nonetheless throw new light on the mysterious nature of dark energy.
