A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter and Saturn are the best-known examples.

In A Nutshell Ancient frozen chemistry: New analysis of pristine samples from asteroid Bennu suggests its amino acids formed ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of fundamental particles heated to trillions of degrees. But this seething primordial ...

As an astronomer, I collect stars. There are several hundred billion of them in our Galaxy, the Milky Way, so it's important to find a way to categorise them. While others might rank their stars by ...

The Radium Hill project is known for its historical uranium production with 2.6Mlb mined during 1954-1961. Previously, the company only had the uranium, scandium and rare earths rights, but a positive ...
