Gravitational lensing is one of astronomy's best tricks for seeing the early universe. When a massive galaxy cluster sits in ...

The James Webb Space Telescope (JWST) has uncovered a distant galaxy where at least 80% of its stellar mass is concentrated ...

Researchers led by a Rutgers University-New Brunswick astrophysicist, who looked deeply into space at a period known as "Cosmic Noon," about 2 billion to 3 billion years after the Big Bang, have found ...

Arp 220 is one of the brightest infrared galaxies in the nearby universe, with intense star formation fueled by a collision ...

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 ...

New MEGATRON simulations connect the first stars and dwarf galaxies, showing how ancient explosions may explain the iron patterns astronomers observe today.

Gas clouds are a common feature of galaxies. Some are classed as high-velocity clouds and we suspected these might account for some of this galactic feeding material. What makes high-velocity clouds ...

Astronomers have discovered a vast, dense cluster of massive galaxies just 1 billion years after the Big Bang, each forming stars at an intense rate from collapsing clouds of dust. Reported in ...

At the heart of most galaxies lies a supermassive black hole — a ginormous entity with a mass so large, it can outweigh millions, if not billions, of suns. According to new research, published in The ...

The largest sample of galaxy groups ever detected has been presented by a team of international astronomers using data from the James Webb Space telescope (JWST) in an area of the sky called COSMOS ...

The process of galaxy merging reshapes cosmic structure by driving dramatic changes in the distribution and state of interstellar gas, thereby governing the rates and locations of star formation.

The formation of galaxies and subsequent stellar evolution within dwarf systems offers a unique window into fundamental processes of cosmic structure growth. Owing to their low masses and relatively ...
