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 ...

An international team of astrophysicists led by the Netherlands and the UK have discovered that radio pulses lasting seconds ...

A supernova is one of the most powerful and mysterious phenomena in the universe. It’s an event that occurs when a star ...

Astronomers have detected mysterious X-ray signals coming from a nearby white dwarf star for more than 40 years. We may now ...

Northwestern University scientists have detected the first radio pulses that can be traced to a dead-star binary.

Ancient ‘white dwarf’ stars explode and die in more ways than was thought, and observing these violent cosmic deaths could help scientists to discover the invisible ‘dark energy’ that is powering the ...

When a white dwarf exceeds a threshold called the Chandrasekhar limit — about 1.4 times the mass of the Sun — it becomes primed to explode. This type of explosion, known as a type Ia supernova, has ...

This zombie star survived a thermonuclear explosion on a white dwarf, challengi... Pa 30 is a fascinating nebula that emerged from a supernova observed in 1181. At its center lies a remarkable ...

"The diversity of ways that white dwarf stars can blow up is much greater than previously expected." There are a lot of ways for dead stars to blow their tops. Astronomers discovered this ...
