When NASA's Osiris-REx spacecraft delivered its sample from asteroid Bennu to Earth in 2023, scientists opened an ancient time capsule. Inside it were grains of dust and rock older than our solar ...

A chemical element that’s not even in H 2 O — sulfur — is the reason Earth first got its water, a new study finds, bolstering a similar claim made a year ago. The discovery means our planet was born ...

The Butterfly Nebula was first discovered in the 1970s, but it's core had been obscured by dust (ESA/Webb, NASA & CSA, K. Noll, J) The James Webb Space Telescope (JWST) has peered through a dense ...
