This discovery is out of this world. For the first time since its operations began in 2021, the James Webb Space Telescope (JWST) has captured a direct image, published by the journal Nature, of a new ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their ...

"We have been waiting for 10 years to confirm that our finely tuned operations of the telescope would also allow us to access the inner planets. Now the results are in, and we can do interesting ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...
