Type Ia supernovae have revealed much about the nature of our universe — including the ... do contain hydrogen because these suns still have ample reserves of unfused hydrogen near their surface.

Rare type Ia supernovas are some of the most energetic events in the universe. Researchers found a consistent pattern of 15 elements in the Hypatia stone, unlike anything in our solar system or in ...

It was shortly confirmed as a Type Ia supernova in the Pinwheel Galaxy, some 21 million light-years distant. That's unusually close by cosmic standards, and the nearest SN Ia since 1986; it was ...

Astronomers have long suspected that this LMC supernova remnant is the remains of a destroyed white dwarf star, but the exact details of that explosive event, called a Type Ia supernova, have ...

We began to suspect Supernova 2020eyj belonged to a rare subclass of Type Ia supernovae in which the blast wave, moving at more than 10,000 kilometers per second, sweeps past gas that could only ...

It has one of the lowest recorded surface brightness levels among ... The scientists behind the study try to explain the lack of X-ray emissions by suggesting Teleios is a Type Ia supernova, ...

A composite image shows the remains of supernova SN 1181, a cataclysmic collision of two stars. The spherical nebula has at its center a hot white dwarf, or "zombie star," left behind after the ...

"If a significant fraction of Type Ia supernovae produce a D6 star, the galaxy has likely launched more than 10 million of them into intergalactic space," the researchers wrote in the study.

In the more common Type Ia supernova, a white dwarf that forms when a sunlike star has exhausted its fuel begins to accumulate material from another nearby star. Many stars exist in pairs, or a ...
