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

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

An artist's impression of how a type Ia supernovae may look as revealed by spectro-polarimetric observations. The outer regions of the blast cloud is asymmetric, with different materials found in ...

Astronomers uncover the first direct evidence for how some white dwarf stars explode, confirming the long-debated ...

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in ...

Astronomers have finally caught a dying star in space going out with a bang — and then another bang. The new photographic ...

Now, they’ve captured the first visual proof: the ancient remnants of a supernova called SNR 0509-67.5 show signs of this ...

Just like the Cepheids come in different varieties, these type Ia supernovae come in different varieties too. A Type Ia supernova in the nearby galaxy M82. This one is fundamentally different from ...

A new analysis of normal type Ia supernovae shows that they have a range of masses and most are near or slightly below the Chandrasekhar mass, and about 1 percent exceed it.

Possessing data regarding more Type Ia supernovas located at different distances from Earth will allow scientists to build a better model of how dark energy is influencing the cosmos.

"This is clearly a very unusual Type Ia supernova." Astronomers have made the first detection of a supernova in radio waves, finding that an exploding white dwarf star was feeding from a companion ...

To firm up the DESI estimate, Scolnic and his team studied 12 different Type Ia supernovae dotted across the Coma cluster.
