Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity streaming long, tentacle-like trails of gas and newborn stars as it speeds ...

NASA announced that its James Webb Space Telescope had spotted its furthest detectable galaxy to date. The announcement marks ...

Astronomers utilizing NASA’s James Webb Space Telescope (JWST) have uncovered a new class of galaxies that defy traditional cosmic categorization. This unexpected discovery, highlighted in a recent ...

A striking new image of our Milky Way's center, captured by the European Southern Observatory's ALMA, spans more than 650 ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Long strands of glowing gas stretch behind a distant galaxy, dotted with pockets of newborn stars. The shape looks almost ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...

A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...

An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate ...

This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the ...

How do you find a galaxy that never formed? The standard cosmological model predicts the existence of “failed” galaxies — clumps of dark matter that captured gas but never birthed a star. Because they ...
