Nothing lasts forever, including the stars in our night sky. One of the brighter and more notable stars in our sky is Betelgeuse, the bright red supergiant in the shoulder of Orion.

In late 2019, astronomers around the world grew giddy with excitement, because we saw this giant star get fainter than we’ve ever seen it before. Since Betelgeuse is at the end stages of its life, there was some speculation this might be a death rattle before the end.

But the cause of the “great dimming” wasn’t ...

Using new computational algorithms, scientists have measured a sharp ring of light predicted to originate from photons whipping around the back of a supermassive black hole.

When scientists unveiled humanity’s historic first image of a black hole in 2019 — depicting a dark core encircled by a fiery aura of material falling toward it — they believed even richer imagery and insights were waiting to be teased out of the data.

Simulations predict that, obscured by that bright orange glow, there should exist a thin, bright ring of light created by photons flung around the back of the black hole by its intense gravity.

Now, a team of researchers has combined theoretical predictions and sophisticated imaging algorithms to “remaster” the ori...

A potentially better way to make oxygen for astronauts in space using magnetism has been proposed by an international team of scientists, including a University of Warwick chemist.

The conclusion is from new research on magnetic phase separation in microgravity published in npj Microgravity by researchers from the University of Warwick in the United Kingdom, University of Colorado Boulder and Freie Universität Berlin in Germany.

Keeping astronauts breathing aboard the International Space Station and other space vehicles is a complicated and costly process. As humans plan future missions to the Moon or Mars better technology will be needed.
