A red supergiant star appears to have changed in just a few years – an astronomical blink of an eye – which suggests it may be getting ready to explode in a supernova

A strange star more than 1300 light years away appears to have two sides with completely different compositions, and astronomers aren’t sure how it ended up that way

The early universe could be home to huge stars powered by dark matter annihilation instead of fusion – and the James Webb Space Telescope may have already found some

Astronomers have found a blast of gamma rays from space that seems to have been caused by two stellar corpses smashing together in a way that’s never been seen before

The stars that orbit close to the Milky Way's supermassive black hole are already tough to explain – but there also seems to be some stars missing

We know there are stars moving fast enough to escape the Milky Way, so the same is probably true of other galaxies. Now, simulations suggest there could be almost 4000 stars from the Andromeda galaxy in the Milky Way today

A distant star called FU Orionis has been shining extraordinarily bright for the last 85 years, and it may be because it is incinerating a young, nearby planet that could be fully consumed in another 300 years
14 June 2023
Astronomers have spotted white dwarfs moving faster than any free-moving star seen before – so fast they must have been launched by supernovae
8 May 2023
Astronomers used the James Webb Space Telescope to spot strange asteroid belts around the nearby star Fomalhaut, along with evidence for at least three planets
3 May 2023
The first stars in our universe may have blown up in relatively weak supernovae, and astronomers believe they have found three clouds of ash remaining from those cosmic explosions
