The Latest Breaking News from James Webb

Deep observations from the James Webb Space Telescope (JWST) have revealed an exceptionally large galaxy in the early universe. It’s a cosmic giant whose light has travelled over 12 billion years to reach us. We’ve dubbed it the Big Wheel, with our findings published today in Nature Astronomy.

The "Cosmic Horseshoe" is an Einstein ring, a system made up of a foreground galaxy whose mass is so great, it warps the light from a galaxy behind it. Now, astronomers know where it gets this mass from.

As black holes slowly vanish through Hawking radiation, their information may be preserved in subtle space-time ripples, a new theory suggests.

"Budget overruns, bureaucratic malfeasance, congressional oversight, review-​board reckonings, the whole process of rethinking how to test a space telescope from the ground up: Webb had survived them all. One other factor, however, continued to create havoc with the budget and the launch timeline deep into the 2010s — what Menzel…

Leaders of NASA sit in an awkward position. While they are the head of a widely recognized organization, they’re often not the most famous individual in the agency. More people probably know the names of Butch Wilmore and Suni Williams, the astronauts currently “stranded” on the International Space Station, than…

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe. New research may explain how they formed, thanks to primordial "seeds".

Astronomers using the James Webb Space Telescope have spotted a feeding black hole in the early universe that seems to be eating 40 times faster than is theoretically possible.
