From how galaxies form to the beginnings of the universe, the images from the space telescope are giving cosmologists new ...

Astronomers have captured an extraordinary new look at the hidden birthplaces of star clusters, uncovering fresh clues about how galaxies evolve — and how young planets may be shaped by their stellar ...

The James Webb Space Telescope captured this image of a young galaxy cluster, MACS J0553.4-3342.

In this July 6, 2026, image, NASA's James Webb Space Telescope's Mid-Infrared Instrument (MIRI) reveals the nearby galaxy ...

The spiral galaxy seen in the top right corner of the image is named Alaknanda, after a river in the Himalayas.

A large protocluster of galaxies that existed 12.6 billion years ago, first discovered with the Subaru Telescope, has been examined in detail using the James Webb Space Telescope (JWST). The study ...

The first images from the largest program in the James Webb Space Telescope’s first year show many types of galaxies, including dazzling examples of spiral galaxies, gravitational lensing, and ...

The finding pushes one of the cornerstones of galaxy evolution much further back in cosmic history than previously known, suggesting that the physical processes shaping galaxies were already at work ...

NASA's James Webb Space Telescope has confirmed that a galaxy cluster 10.4 billion light-years away is the most distant strong gravitational lens ever observed — and that its dark matter core is ...

New James Webb Space Telescope images now show how that fuel returns, tracing a filament directly into a rotating disk around one black hole. The observations focus on NGC 4696, the central galaxy of ...

JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696. A vast filament appears to funnel material into an 800-light-year-wide spinning disk, ...
