Galaxy clusters are the heaviest structures in the universe, yet most of their mass is invisible, inferred only from the way it tugs on light and galaxies. Now a new class of “dead” stars, white ...

Qiong Li's research on JADES-ID1 offers new perspectives on the formation of galaxy clusters, challenging traditional views ...

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international ...

Galaxy clusters, the largest structures held together by gravity in the universe, may be far heavier than scientists once ...

What: New analyses using early observations from the European Space Agency’s Euclid mission examine how galaxy mergers trigger active galactic nuclei (AGN), luminou ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields ...

Galactus, the Devourer of Worlds, embodies the concept of cosmic balance through consumption. His hunger is not mere gluttony but a n ...

Dark matter doesn’t seem to interact with the matter we can see and touch, so scientists look for it in unusual places, like faraway galaxies and underground detectors.

Astronomers using the James Webb Space Telescope (JWST) have discovered galaxies colliding in the early universe, revealing that cosmic structures are far more complicated than astronomers once ...

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth&rsquo ...

The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big ...
