Getting in a spin: Record-breaking white dwarf star completes a full rotation once every 25 SECONDS - four seconds faster than the previous record-holder The star, called J0240+1952, is the fastest spinning confirmed white dwarf It is the same size of Earth, but is thought to be at least 200,000 more massive The star is pulling gaseous plasma from a nearby companion star and flinging it into space at speeds of around 1,864 miles/second (3,000 kilometres/second)

A white dwarf star has broken records after scientists discovered that it completes a full rotation once every 25 seconds.

The star, called LAMOST J024048.51+195226.9 (or J0240+1952 for short), was analysed by researchers from the University of Warwick, who say it is the fastest spinning confirmed white dwarf.

The previous record holder was a white dwarf that completed a rotation in just over 29 seconds, making J0240+1952 20 per cent faster.

Dr Ingrid Pelisoli, who led the study, said: 'J0240+1952 will have completed several rotations in the short amount of time that people take to read about it, it is really incredible.'

WHAT IS A WHITE DWARF? 

A white dwarf is the remains of a star that has run out of nuclear fuel.

Stars larger than 10 times the mass of the sun suffer a violent supernova at the end of their lives, but a more gentle end awaits sun-like stars. 

When stars like the sun come to the ends of their lives they exhaust their fuel, expand as red giants and later expel their outer layers into space.

The hot and very dense core of the former star - a white dwarf - remains.

White dwarfs contain approximately the mass of the sun but have roughly the radius of Earth.

A white dwarf is a star that has burned up all of its fuel, and is beginning to shed its outer layers.

This particular white dwarf is around the same size of Earth, but is thought to be at least 200,000 more massive.

In the study, the team studied J0240+1952 using the highly sensitive HiPERCAM instrument on the 10 metre-wide Gran
