The young galaxy cluster existed about 12.8 billion years ago and has an estimated mass 20 trillion times that of the sun ...

Astronomers have spotted a mysteriously mature “baby cluster” of galaxies in the early universe, scarcely a billion years ...

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 ...

Under the leadership of the University of Bonn, a research team led by Prof. Dr. Pavel Kroupa from the Helmholtz Institute for Radiation and Nuclear Physics has discovered that galaxy clusters are ...

WASHINGTON, Jan 30 (Reuters) - Observations by NASA's James Webb Space Telescope and Chandra X-ray Observatory are providing ...

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

"JADES-ID1 is giving us new evidence that the universe was in a huge hurry to grow up." ...

How space telescopes capture distant galaxies using infrared imaging, precision optics, and astronomy technology beyond Earth ...

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.

Roughly 2.8 billion light-years from Earth, two galaxy clusters are engaged in a cosmic tussle. These enormous structures last collided about a billion years ago, but now, it appears they’re going ...

New X-ray imaging method maps sound waves, shocks, bubbles and cooling gas in galaxy clusters, revealing stronger black hole feedback in groups. (Nanowerk News) Galaxy clusters are the most massive ...

Scientists discovered that galaxy clusters are about twice as heavy as previously assumed. The additional mass comes mainly from neutron stars and stellar black holes and also explains the observed ...
