'The bottom line is, I told you so': JWST observations upend standard model of how galaxies form, new study claims

By Ben Turner published

The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for how physics may work on large scales, according to a team of astronomers.

James Webb Space Telescope discovers mysterious 'red monster' galaxies so large they shouldn't exist

By Ben Turner published

The James Webb telescope has spotted three gigantic "red monster" galaxies that were spawned soon after the Big Bang. They're so large they could rewrite the laws of galactic evolution.

Space photo of the week: Hubble spies a 'cannonball galaxy' blasting through space

By Jamie Carter published

The Hubble Space Telescope has captured a spiral galaxy under the "ram pressure" inside a massive cluster of galaxies.

A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colors reflecting different types of star. Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black.

42 jaw-dropping James Webb Space Telescope images

The Milky Way could be part of a much larger 'cosmic neighborhood' than we realized, challenging our understanding of the universe

By Harry Baker published

A probabilistic new map of the universe surrounding the Milky Way reveals that our galaxy is likely part of an even larger "basin of attraction" than we previously assumed.

Space photo of the week: Entangled galaxies form cosmic smiley face in new James Webb telescope image

By Jamie Carter published

A new image from the James Webb Space Telescope shows Arp 107, home to two merging galaxies, with two bright cores and a "bridge" of dust and gas forming a cosmic smiley face.

The Andromeda Galaxy glows rosy red in gorgeous new Hubble Telescope image

By Samantha Mathewson published

The Andromeda Galaxy, the Milky Way's closest galactic neighbor, glows brightly in a new Hubble Space Telescope image with swathes of ionized gas that fuel star formation.

What??? James Webb telescope finds giant question mark in space

By Brandon Specktor published

Astronomers using the James Webb Space Telescope have discovered a pair of distant galaxies being twisted into a cosmic question mark thanks to a rare form of gravitational lensing.

Artist's concept of a supermassive black hole.

The James Webb telescope found hundreds of 'little red dots' in the ancient universe. We still don't know what they are.

By Fabio Pacucci published

These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.
