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 ...

What Is a Supernova?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 ...
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 Chinese–European Einstein Probe. This nova is especially ...
White dwarfs typically have a radius just ... runaway fusion occurs and the star will detonate in a thermonuclear supernova.
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 ...
before it becomes a white dwarf. Yet, a star of 12 solar masses should explode as a supernova after just 20 million years. So, given the huge difference in lifespans, how can this Be star find ...
