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 ...

The expansion of the Universe, discovered nearly a century ago by Edwin Hubble, shows that galaxies are moving away from us faster the more distant they are. Yet, our nearest neighbor, the ...

A recent study proposes that the peculiar behavior of galaxies could be due to gravity functioning differently at vast cosmic scales, challenging the existence of dark matter.

Across the quiet darkness of space and the buried detectors under Antarctic ice, a set of stubborn anomalies is piling up.

NASA has confirmed its sightings of the farthest known galaxy to date, providing an unprecedented look back into the early universe about 280 million years ...

Since conventional explanations have failed to pony up dark matter, one physicist is looking towards the unconventional. In a series of two papers, physicist Stefano Profumo of the University of ...

The XRISM science team, including members of Nagoya University, has explained how galaxy clusters maintain their heat despite emitting X-rays, which typically have a cooling effect on the hot gas. By ...

A team of astronomers from the University of Geneva used the James Webb Space Telescope (JWST) to spot the most distant quiescent galaxy ever found. The discovery, made just 700 million years after ...

NASA's James Webb Space Telescope has revealed yet another marvel from deep in outer space. A galaxy named MoM-z14 has taken the title of most distant galaxy the telescope has captured. It is a ...

A new gravitational model suggests dark matter may not exist. By allowing gravity to weaken more slowly at large distances, physicist Naman Kumar shows galaxy rotation curves can be explained using ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

NASA confirms galaxy MoM-z14 observed by the James Webb Space Telescope formed 280 million years after the Big Bang using ...
