Experiments point the way to solving mystery that keeps clusters hot. Galaxies rarely live alone. Instead, dozens to thousands are drawn together by gravity, forming vast clusters that are the largest objects in the universe.

“Galaxy clusters are one of the most awe-inspiring things in the universe,” said Prof. Emeritus Don Lamb, a University of Chicago astrophysicist and co-author on a new paper published March 9 – one that may point the way towards solving a decades-long mystery.

Scientists have long known that the hydrogen gas in galaxy clusters is searingly hot – about 10 million degrees Kelvin, or roughly t...

Have you ever gotten relief from summertime heat by draping a wet towel over your head? If so, you’ve benefited from a phase-change material (PCM): a substance that releases or absorbs energy when it ...

Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution, now published in Nature, involves a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away.

Black holes are one of the most fascinating objects in the Universe, but our knowledge of them is still limited — especi...

Researchers at the University of California, San Francisco, have successfully leveraged an FDA-approved drug to halt growth of tumors driven by mutations in the RAS gene, which are famously difficult to treat and account for about 1 in 4 cancer deaths.

Taking advantage of what they discovered to be the cancer cells’ appetite for a reactive form of iron, the researchers tweaked an anticancer drug to operate only in these iron-rich cells, leaving other cells to function normally...
