Scientists discovered a distant jellyfish galaxy with star-forming "tails" stretching back 8.5 billion years.

Astronomers have unveiled a new catalog of massive galaxy clusters, revealing insight on the evolution of the universe. Galaxy clusters — the largest gravitationally bound structures in the universe — ...

Using data from the Hubble Space Telescope, ESA’s Euclid space observatory, and Hawaii’s Subaru Telescope, the researchers discovered faint light emitting around the clusters. That light was clear ...

A rare jellyfish galaxy discovered by JWST is offering clues about how galaxies died in the early universe.

When a galaxy is born, it is cool and immature, much like a baby. Over the initial million years of its life or so, it feeds on the heat energy of neighboring stars and celestial objects, often ...

Scientists led by a team from the University of Chicago recently released a study that mapped some of the largest known objects in the universe. The study may help scientists test theories about how ...

A team of astronomers has identified an extremely faint galaxy called CDG-2, located roughly 300 million light-years from Earth, where an estimated 99% of its total mass is made of invisible dark ...

New model shows extremely massive stars, over 1,000 solar masses, shaped the birth and early evolution of the universe's oldest star clusters. (Nanowerk News) An international team led by ICREA ...

Light takes time to travel through space. Because of this, the light we see from distant objects in the night sky represents what they looked like when they released this light, not necessarily what ...
