In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly ...
Explosions in the sky and explosions on land are literally worlds apart. A supernova and a land mine explosion don't seem ...
This can trigger a supernova in two ways. Firstly, the collision itself can create a larger white dwarf and a type Ia supernova. Alternatively, the stellar remnant this creates can birth a ...

A flash of powerful X-ray light coming from a nova explosion on a white dwarf star has caught the attention of astronomers using the ChineseāEuropean Einstein Probe. This nova is especially ...
Astronomers have detected mysterious X-ray signals coming from a nearby white dwarf star for more than 40 years. We may now ...
When a white dwarf exceeds a threshold called the Chandrasekhar limit ā about 1.4 times the mass of the Sun ā it becomes primed to explode. This type of explosion, known as a type Ia supernova, has ...
Ancient āwhite dwarfā stars explode and die in more ways than was thought, and observing these violent cosmic deaths could help scientists to discover the invisible ādark energyā that is powering the ...
