Images taken with the MIRI infrared camera on the James Webb Space Telescope (JWST) have made it possible to observe the first galaxies in long-wavelength infrared light for the first time. Alongside ...

Illustration of the underlying astrophysical processes that suppress star formation in red geyser galaxies, according to this new study. Galaxy interactions transfer cool gas clouds that fall into ...

The “little red dots” discovered by the James Webb Space Telescope (JWST) pose a cosmic conundrum. It seems that these compact galaxies are either stuffed impossibly full of stars or have black holes ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

NASA’s Chandra X-ray Observatory has detected the first X-ray emissions from a 'little red dot' galaxy, 3DHST-AEGIS-12014, located 11.8 billion light-years away. This rare observation links mysterious ...

Impossibly bright galaxies discovered by the James Webb Space Telescope (JWST) may not be so bright after all. These galaxies once threatened to upend our understanding of the cosmos by suggesting it ...

This image combines data from the JWST's MIRI and NIRcam cameras to create a multicolour view of the Hubble Ultra Deep Field. The the green, orange, and red hues come from MIRI and reveal the reddest ...

Astronomers have long puzzled over how some massive galaxies stop forming stars and remain dormant for billions of years—even when they still contain gas that could, in principle, fuel new stars. A ...
