All solar system planets circle our sun with slightly tilted orbits — and a new study shows even distant planetary systems in quiet neighborhoods have orbital tilts, too.

Amazon Web Services this week introduced Trainium2, its new accelerator for artificial intelligence (AI) workload that tangibly increases performance compared to its predecessor, enabling AWS to train foundation models (FMs) and large language models (LLMs) with up to trillions of parameters. In addition, AWS has set itself an ambitious goal…

JUICE blasted off in April 2023 on a mission to explore Jupiter’s ocean moons and learn more about whether they could support life.
