Will two rare supernovas finally tell us how fast the universe is expanding? Perhaps, but we'll have to wait for it for them ...

Recent James Webb Space Telescope data confirms a decade-old theory that the universe's earliest supermassive black holes ...

NASA’s James Webb Space Telescope (JWST) has captured images of a distant galaxy that is forming a peculiar cosmic structure ...

Dark matter is a mysterious substance that glues galaxies together. This map from the James Webb Space Telescope could help ...

JWST observations of galaxy cluster MACS J1149 show gravitational lensing used by CANUCS to study distant low-mass galaxies across a wide range of cosmic time.

Dark matter seems invisible, but it makes up most matter, and we have evidence that it gives the cosmos its shape. Now ...

JWST images reveal hidden stars, dusty galaxies, and cosmic timelines. See why Webb’s infrared vision is rewriting ...

The observed near flatness of galactic rotation curves has long been interpreted as evidence for large amounts of non-baryonic dark matter. Here we show that this phenom ...

The Dark Energy Survey catalogued 669 million galaxies, using 140 million for precise measurements to help understand why the universe's expansion is accelerating rather than slowing down.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month brings us a scene from the distant universe. Pictured here ...

Lensing in action: A montage of eight time-delay gravitational lens systems. There is an entire galaxy at the centre of each image, and the bright points in rings around them are gravitationally ...

Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, ...
