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

Astronomers captured newly released photos of inside the heart of spiral galaxies with infrared light, which is invisible to ...

Light from young stars could push away gas and dust, exposing bright early galaxies. New calculations show why dense stellar ...

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

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 ...

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

Galaxies evolve through a complex interplay between the gravitational motions of stars, the behaviour of the interstellar medium (ISM) and the processes that govern the collapse of cold gas into new ...

Three unusual dwarf galaxies near the Pinwheel Galaxy may help astronomers test long-standing ideas about galaxy evolution ...

The formation of galaxies by gradual hierarchical co-assembly of baryons and cold dark matter halos is a fundamental paradigm underpinning modern astrophysics 1,2 and predicts a strong decline in the ...

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 ...

Stars Make Oxygen for Small Galaxies. They Lose Most of It.

Astronomers think black holes reside at the center of most, if not all, galaxies. And on February 16, 2026, the University of Arizona said the intense radiation they emit can slow star growth. Not ...
