 The James Webb Space Telescope peered into one of the universe’s oldest galaxy clusters, and scientists can’t explain what they saw

Using the James Webb Space Telescope, astronomers have spotted a massive and densely packed galaxy cluster at “cosmic noon” before such structures were thought to be possible.

 Strange glowing ‘bow-and-arrow’ structure may be a giant cosmic shock wave created by a supersonic galaxy collision

A bizarre “bow-and-arrow” radio galaxy nearly 1.8 million light-years across could reveal how galaxy clusters sculpt some of the universe’s largest structures.

Millions of Stars in Cigar Galaxy
 Millions of Stars in Cigar Galaxy

NASA’s James Webb Space Telescope recently observed edge-on starburst galaxy Messier 82 (M82), nicknamed the Cigar Galaxy. Webb’s new view of M82, added to archival data from NASA’s Hubble Space Telescope, gives us a more complete picture of this starburst galaxy. Because Webb can see infrared light, it is able to peer through clouds of […]

 NASA’s Webb Pinpoints Millions of Stars Within Cigar Galaxy

Located 12 million light-years away and undergoing rapid star formation, edge-on spiral galaxy Messier 82 (M82) is a scientifically unique sight to behold, and now NASA’s James Webb Space Telescope has revealed previously unseen details. M82’s intense star formation, thought to be the result of a galaxy merger, will be a short-lived event in astronomical […]

James Webb Space Telescope discovers ‘galaxy-killing’ wind that may explain why some early galaxies lived fast and died young

A “galaxy-killing” wind driven by cosmic mergers may explain why many massive galaxies in the early universe stopped forming stars far earlier than expected, according to new JWST and ALMA observations.

Do galaxies have a ‘kill switch’ that makes them stop growing?

Above a certain threshold, galaxies stop growing , no matter how much raw material they have on hand. The question is: what flips the switch?

Trouble near the Milky Way: The Large Magellanic Cloud is ripping its smaller neighbor galaxy apart

The Magellanic Clouds are a pair of dwarf galaxies passing the Milky Way probably for the first time, but as they move they have been interacting with each other for billions of years.
