The Latest Breaking News from JWST

Can the James Webb Space Telescope see galaxies over the universe's horizon?

The James Webb Space Telescope has revolutionized astronomy in just two years of operations, but how can it see a galaxy 33.8 billion light-years away in a universe that is only 13.8 billion years old?

Extreme 'hot Jupiter' exoplanet stinks like rotten eggs and has raging glass storms

As if deadly rains of glass, temperatures hot enough to melt lead, and sidewise 5,000 mph winds weren't unfriendly enough, the JWST has found a Jupiter-sized exoplanet also stinks of rotten eggs.

'Supernova discovery machine' James Webb Space Telescope finds most distant star explosion on record

The JWST has proven itself to be a "supernova discovery machine" by finding 80 exploding stars in the infant universe, including the most distant and earliest supernova ever seen.

James Webb Space Telescope spots asteroid collision in neighboring star system

The James Webb Space Telescope has seen signs of a violent asteroid collision in neighboring star system, Beta Pictoris. The observations could reveal the early stages of planet birth.

Rocky, carbon-rich exoplanets more likely around tiny stars, James Webb Space Telescope reveals

Astronomers using the JWST have discovered tiny stars may be better suited at birthing small, rocky planets with atmospheres dominated by carbon.

James Webb Space Telescope spots the most distant galaxy ever seen (image)

James Webb Space Telescope has spotted the two earliest and most distant galaxies ever seen. One, JADES-GS-z14-0, is a massive and bright galaxy that existed just 300 million years after the Big Bang.

New Data from JWST Reveals How Galaxies Grew In the Early Universe

“These galaxies are like sparkling islands in a sea of otherwise neutral, opaque gas,” says Heintz in a recent statement. New JWST data shows just that.

This diamond exoplanet lost its atmosphere — then it grew another

55 Cancri e is a super-Earth planet that appears composed of diamond-like carbon — now, thanks to the JWST, astronomers have found the world has "grown" a second atmosphere.

Did the James Webb Space Telescope really find life beyond Earth? Scientists aren't so sure

Despite excitement last year, the James Webb Space Telescope probably hasn't detected life on a distant super-Earth exoplanet with life signs detected on potential ocean world K2-18 b likely premature.

No, the James Webb Space Telescope probably didn't detect signs of alien life — but it soon could

The James Webb Space Telescope's possible detection of biological chemicals on the exoplanet K2-18b may just have been methane gas, a new study cautions. Planned follow-up observations could solve the mystery for good.

James Webb Space Telescope forecasts clouds of melted rock on this blisteringly hot exoplanet

The JWST has performed a weather report for a distant hot Jupiter exoplanet, finding winds three times as fast as a jet fighter, clouds made of rock and temperatures hot enough to melt lead.
