A supernova explosion occurred on July 4, 1054, resulting from the death of a star estimated to be nine to eleven times the ...

"The explosions of white dwarfs play a crucial role in astronomy," stated Priyam Das, a PhD student at the University of New South Wales Canberra and study leader. Das further described the findings ...

Type Ia supernovae are triggered by white dwarfs—the fading cores of dead stars. These stellar corpses often steal matter ...

The largest and brightest is an enormous supergiant star about 100 times the mass of the Sun and five million times brighter.

Galaxies have an overall internal motion called disk velocity. It’s how gas, dust, and stars move around the galactic center.

The "new stars" are best seen from the Southern Hemisphere, but people have spotted them from the United States by looking ...

Researchers have used machine learning to dramatically speed up the processing time when simulating galaxy evolution coupled with supernova explosion. This approach could help us understand the ...

Less than two weeks later, on June 25, reports began to circulate of a second nova blossoming in the southern night sky, this time in the constellation Vela. This nova — later designated V572 Velorum ...

The shattered star at the center was once a white dwarf, a stellar ember no larger than Earth, yet almost as heavy as the Sun ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

This is the first evidence for a white dwarf exploding not once, but twice. The discovery could shed new light on how some ...
