In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly ...

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 ...

Explosions in the sky and explosions on land are literally worlds apart. A supernova and a land mine explosion don't seem ...

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

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

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

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

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 ...
