For all the impressive maps astronomers have made of the distant universe, much of the action has stayed out of sight. The brightest galaxies were relatively easy to chart. The faint hydrogen glow ...

Astronomers peering back deep in time into the distant universe think they may have discovered a population of previous hidden galaxies that could shake up astrophysics. The research, based on data ...

Using the James Webb Space Telescope, scientists spotted thin and thick disks in galaxies as far back as 10 billion years ago—something never seen before. These observations reveal that galaxies first ...

An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion ...

Astronomers at MIT, Columbia University, and elsewhere have used NASA's James Webb Space Telescope (JWST) to peer through the dust of nearby galaxies and into the aftermath of a black hole's stellar ...

The final SPIRE Dark Field image map created by combining the Blue (250 micrometres), Green (350 micrometres) and Red (500 micrometres) SPIRE camera channels together, each channel stacking a total of ...

For years, astronomers have been working to piece together the story of our universe, but the critical early chapters remained largely incomplete. Our telescopes simply haven't been sensitive enough ...

"We've always known that we need something to complete the puzzle, but we haven't really known what shape or form those missing pieces were going to be." When you purchase through links on our site, ...

Researchers discovered a hidden 185,000 light-year "bridge" of gas between two distant galaxies, which are also trailed by a 1.6 million light-year galactic tail — the largest of its kind ever seen.

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...
