'Superbubbles' of gas around quasars may form thanks to powerful winds
12 July 2023
Colossal bubbles of hot gas observed around three distant, supermassive black holes are probably the result of powerful winds, which could also be preventing the formation of new stars in those galaxies
The Milky Way could contain thousands of stars from another galaxy
22 June 2023
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
What the huge young galaxies seen by JWST tell us about the universe
13 June 2023
A few months ago, the James Webb Space Telescope spotted six early galaxies that were so large they threatened to break our best theory of how the cosmos evolved. Did they?
Fast-growing galaxy seen by JWST offers window on the early universe
12 June 2023
A galaxy seen 700 million years after the big bang appears surprisingly mature, suggesting some pockets of the early universe were more tranquil than expected
We are finally closing in on the cosmic origins of the “OMG particle”
30 May 2023
Three decades ago, we spotted the single most energetic particle ever seen, nicknamed the 'Oh-My-God particle'. Since then, we have seen many more ultra-high-energy cosmic rays – and now we are unravelling the mystery of what produces them
JWST has spotted the most distant galaxy cluster ever seen
24 April 2023
The James Webb Space Telescope has found the most distant galaxy cluster ever seen, at 30 billion light years away. Researchers say it’s probably one of the biggest clusters in the universe by now

An abridged inventory of everything there is in the universe – from rogue planets and exomoons to supernovae, supermassive black holes and the cosmic web.
A supermassive black hole is hurtling away from its home galaxy
7 April 2023
For the first time, researchers have spotted what appears to be a supermassive black hole flying away from its home galaxy at incredible speeds, trailing bursts of star formation behind it
Galaxy may have eaten all its neighbours and now it's all alone
15 March 2023
Astronomers have spotted an object with all the hallmarks of a galaxy cluster, but containing only one galaxy – hinting it may have swallowed up all of its neighbours
