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.

Space photo of the week: Hubble spies a spectacular galaxy crash

By Jamie Carter published

Arp 107 hosts a special spiraling 'Seyfert' galaxy connected to a smaller galaxy by a 'bridge' of dust and gas.

In the field of one of JWST's largest-area surveys, COSMOS-Web, an Einstein ring was discovered around a compact, distant galaxy. It turns out to be the most distant gravitational lens ever discovered by a few billion light-years.

Stunningly perfect 'Einstein ring' snapped by James Webb telescope is most distant gravitationally lensed object ever seen

How many planets are in the universe?

By Briley Lewis published

We currently know of 5,502 planets beyond the solar system, but we've only found the tiniest fraction of the planets astronomers think lie elsewhere in the universe.
