A new study confirms that Tycho Brahe saw a common kind of star explosion that involves the explosion of a white dwarf star with a nearby companion in 1572.
Astronomers have spotted the most distant and oldest star explosions yet in the universe.
... have at last found definitive evidence that the universe's first dust -- the celestial stuff that seeded future generations of stars and planets -- was forged in the explosions of massive stars.
... from catching a supernova at the very onset is already being hailed as the 'Rosetta Stone' of star explosion, and it is helping scientists to form a detailed picture of the processes involved. A ...
A spectacular nearby star explosion observed in 1843 is now thought to be related to a class of distant supernova imposters that seem to explode periodically yet remain intact.
... driven by the stellar wind, but an actual explosion deep in the star that sent debris hurtling into interstellar ... intense light pushes the outer layers of the star away in a stellar wind. After 2 to 3 ...
WASHINGTON (Reuters) - A gigantic explosion of a star halfway across the universe long ago aimed a burst of gamma rays directly at Earth, an international team of scientists said on Wednesday.
... of how stars evolve. Our analysis also suggests that the combined mass of the two stars which produced the explosion could be high enough that eventually, the two stars will spiral into each other, ...
Cosmic "dust bunnies" hiding in corners of distant galaxies are taking the dazzle out of some of the universe's brightest explosions, new research suggests.
... it certainly needs to be taken seriously.
"The implications are quite important. If this is a massive star explosion then it is the first one that might fit the theoretical models of massive stars ...
... by the way "antimatter positrons" from the radioactive decay of elements, created by massive star explosions in the galaxy, propagate through the galaxy. Thus, the scientists said, the observed ...
From galaxy cluster pileups to star explosions, things aren't always nice and quiet in outer space. Jupiter's recent black eye just adds to this list of bouts of intergalactic violence.
Star explosions accelerate high-energy particles called cosmic rays, sending them darting across space, according to a new study of gamma ray-filled galaxies.
A star explosion that blazed as bright as ten billion suns but faded away within 20 days might be the first proof of a theoretical new class of supernova, astronomers suggest.
