A galaxy cluster can be thought of as a slow-built machine: gravity assembles the parts, time warms the coolant, and only later does the system settle into the kind of hot, stable “atmosphere” seen in ...

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

Gas within the cluster, which existed merely 1.4 billion years after the Big Bang, is at least five times hotter than ...

JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from Cambridge studied over 250 galaxies and found most were turbulent, still forming ...

The Galaxies Showcase 2025 is nearly here, and it's set to feature more than 50 games, six world premieres, exclusive reveals, demo drops, and so much more. There is a lot to look forward to, and ...

Unexpectedly violent black holes may have caused the mystery of the missing cosmic matter. Most of the universe is filled with mysterious dark matter, but even ordinary matter has stumped cosmologists ...

Lister Staveley-Smith receives research funding from ICRAR, the Western Australian government, and the University of Western Australia. Most of the ordinary matter in the universe is hydrogen. But ...

The vastness of space allows for a huge variety of structures to pop up all over the place. Even things we think of as one-and-done objects—like galaxies—come in quite a few shapes and sizes. Follow ...

While nearly all massive galaxies possess central black holes, the presence of such black holes in dwarf galaxies remains an open question, with previous estimates identifying them in only 0.5% of ...

A weird type of galaxy seen in the early universe has now been spotted in a more recent part of the cosmos, raising questions about their true nature. Over the past few years, astronomers using the ...
