A new JWST study finds early galaxies at redshift 6–10 may be nearly as old as the universe at that time. One galaxy even appears older than cosmic age estimates, potentially challenging the standard ...

XRISM measurements map gas velocities in the Perseus and Virgo clusters, separating black hole-driven turbulence from merger-driven motion using high-resolution X-ray spectroscopy.

New research reveals how quiet galactic engines can help shape entire galaxies.

According to general relativity, gravity is the distortion of spacetime. Heavyweight cosmic entities like stars or galaxies ...

Hubble catches a spiral galaxy mid-flight, shedding glowing gas as it battles the harsh environment of a nearby galaxy ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

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 ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don’t ...

Deep inside a nearby galaxy, a black hole sits behind a thick wall of dust. Almost all its light gets trapped.

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