When it comes to artificial intelligence, more intensive computing uses more energy, producing more greenhouse gases.

• Tracing the origin of an ultra-hot exoplanet: The chemical composition of WASP-121b suggests that it formed in a cool zone of its natal disc, comparable to the region of gas and ice giants in ...

No telescope has basked in the night sky quite like the enormous new Vera Rubin Observatory. Here's what it could reveal ...

Scientists aimed ALMA at the comet in March 2024 and saw carbon monoxide — a gas that usually doesn’t show up in observations that far away — gushing out of its surface in jets. The team also picked ...
