The oldest ever black holes, a preview of our solar system's gory demise, and a measurement of distant starlight that threatens to bring the standard of cosmology crashing down — here are the JWST's wildest discoveries of 2023.
Hubble Telescope captures a galaxy's 'forbidden' light in stunning new image
By Samantha Mathewson published
The Hubble Telescope viewed a distant galaxy whose light appears to contradict some of the most common rules of quantum physics.
Intergalactic 'stream of stars' 10 times longer than the Milky Way is the 1st of its kind ever spotted
By Harry Baker published
While hunting for dark matter, astronomers accidentally discovered the first known stellar stream stretching between galaxies. The trail of stars is also the longest ever seen.
'Teenage' galaxies from the early universe contain mysterious heavy elements, James Webb telescope reveals

Tiny galaxies that had their stars stolen could be a 'missing link' in cosmic evolution
By Robert Lea published
More than 100 observed galaxies are being disrupted and stripped of their outer layers, transforming them into fossil-dense, ultra-compact dwarf galaxies.
James Webb telescope's observations of 'impossible' galaxies at the dawn of time may finally have an explanation
By Ben Turner published
A new set of simulations suggests that the unusual brightness of early galaxies discovered by the James Webb telescope could be because of a strange, rapid-burst mode of star formation.
