Researchers at the University of British Columbia and Dalhousie University have found a young galaxy cluster that appears far ...

How could the Universe form such dense and extremely hot structures only 1.4 billion years after the Big Bang? This question ...

The galaxy cluster appears hotter and more mature than it should for its young age, challenging what we think we know about ...

An international team led by Canadian astronomers has found a galaxy cluster blazing with hot gas just 1.4 billion years ...

Most astronomers agree that young galaxy clusters should be relatively cool compared to older ones. But researchers recently ...

Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe.

The cluster hosts a reservoir of gas so hot it has left scientists rethinking their understanding of how galaxies form and ...

A new study finds that galaxy clusters — cosmic cities packed with thousands of galaxies — trace invisible highways of dark matter stretching up to a billion light years across the universe. Even more ...
