Will Sirius B explode as a type Ia supernova?
Could the nearby star Sirius B explode as a type Ia supernova, like some other white dwarf stars in binary star systems have? Bruce Mason Encinitas, California A type Ia supernova occurs when a white ...
The 2-m aperture Chinese Space Station Telescope (CSST), which observes at wavelengths ranging from 255 to 1000 nm, is expected to start science operations in 2024. An ultra-deep field observation ...
Astronomers have discovered evidence that could help solve a long standing dispute over the origin of Type Ia supernovae, by observing the youngest example of the titanic explosions located to date.

For the first time, astronomers have caught a type Ia supernova being magnified by more than 50 times and split into four images in the night sky thanks to gravitational lensing. The discovery, ...
Type Ia supernovae result from a white dwarf exceeding 1.4 solar masses after accreting hydrogen from a companion star, leading to a thermonuclear explosion. The Sirius system contains a white dwarf ...
