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 — ...

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

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 fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar ...

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 ...

A newly discovered galaxy cluster could rewrite our understanding of the cosmos, as scientists spot 'something the universe wasn’t supposed to have’. Researchers found that the cluster was burning ...

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 ...

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 ...

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 ...

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 ...
