A team astronomers discovered a supernova imposter that, oddly, was giving off a fierce amount of X-rays.
100 years after Einstein presented his theory of general relativity to the world, the presence of gravitational waves has been detected for the first time.
On 3 December 2015, ESA’s LISA Pathfinder lifted off from Kourou in French Guiana as part of a new mission to prepare for the future detection of gravitational waves. Astronomer and science writer Govert Schilling investigates.
The mystery of a 'distubred' spiral galaxy may have been solved, following the discovery of an elongated dwarf nearby.
Today, ESA will announce the events taking place this year on 30 June to mark the second ever Asteroid Day. Follow the announcements, as they happen, in the window below.
Studies of a protoplanetary disc surrounding a young star have revealed that dust grains in the outer edges of the disc are much colder than expected.
Studies of Saturn’s B ring have shown little correlation between how opaque or dense certain areas appear to be and the amount of material present, adding to the mystery of how the ringed planet’s prominent features formed.
The Moon is the product of a violent, head-on collision between Earth and a planetary embryo called Theia that occurred about 4.5 billion years ago, according to a new study.
The presence of different generations of stars within the same globular cluster could be explained by the clusters ‘adopting’ other stars rather than creating them, according to a new study.
Thirty years ago today, on 28 January 1986, Space Shuttle Challenger launched from Kennedy Space Center on a planned mission to deploy a data relay satellite and carry out several science experiments, including observations of Halley's Comet.
It has long been inferred by astronomers that the heavier a galaxy cluster is, the more dark matter is in its environment. But new studies are revealing that the relationship between the two could be even more intricate.
A study of the Milky Way has revealed invisible structures shaped like ‘noodles’ could be floating in the gas that exists throughout the Galaxy.
Since the declassification of Pluto in 2006, our Solar System has been considered an eight-planet system. But a new discovery by astronomers may have revealed a new contender for the ninth member.
The use of radio telescopes is helping astronomers at the National Astronomical Observatory of Japan uncover hidden black holes within the Galaxy. Their latest discovery could be a vital piece in the puzzle as to how supermassive black holes are formed.
Tim Peake has become the first ESA-sponsored British astronaut to complete a spacewalk during a mission to replace a failed power generator.
Turbulence caused by a supermassive black hole at the centre of a galaxy is causing ionised gas to be blown in all directions.
Preparation is underway for Tim Peake's first spacewalk, taking place today at 12:55 UTC. Tune in to Stargazing LIVE tonight at 9pm with Professor Brian Cox and Dara O'Briain to see how Tim got on.
A powerful new telescope instrument that will look at the environments surrounding black holes has met expectations by making a discovery during its initial tests.
Observations have been made of a bright quasar over a 12-year period, giving astronomers insight into a unique and dramatic process at work.
Using a new discipline called galactoseismology, astronomers have been able to posit for the first time the cause of ripples in the outer disc of the Milky Way.
