A white dward (centre) and its companion pulsar make for an excellent natural gravitational laboratory.
One of Einstein's weirder predictions is that massive, spinning objects exert a drag on space-time itself. Now an orbiting pair of unusual stars has revealed this effect in action.
Radio flare may be the result of a giant star orbiting some unusual object – a combination we have never seen before.
Searching for planets around nearby stars is like searching for a needle in a field of haystacks.
Science is full of surprises. While searching for planets orbiting nearby stars, researchers stumbled across the remains of a star that once outshone the Sun.
What’s left after a star explodes.

By studying old and dead stars, we can discover what will happen to our sun in the far, far future. And it won't end with a big explosion.

Exoplanet discovery can help us work out how the Earth will end its days.
The ALMA telescope has seen tantalising hints of a violent event.

The 'oldest known nova' (a star explosion) in the sky was actually not a nova, astronomers show.
A disintergating asteroid caught in the gravitational pull of a white dwarf star: could this be the future fate of the Earth?

A study into a distant white dwarf could help us learn more about the future fate of the Earth – and it could be a violent one.
Artist’s view of a watery asteroid heading to a white dwarf star.
The discovery of a white dwarf star with hydrogen and oxygen in its atmosphere suggests water could be planted on stars and planets by bodies like asteroids.
Artist’s impression of two white dwarf stars destined to merge and create a Type Ia supernova in 700-million years time.
Two white dwarfs found orbiting each other at the centre of a planetary nebula are now known to have enough mass that they will eventually trigger a special kind of supernova, according to research published…
