Geologists have found that an ancient meteorite hit Scotland 200 million years later than previously thought, which has massive implications for the geological history of the region and some of the U.K.'s earliest land life.

The dinosaurs were not in decline before the asteroid hit, a new study finds. Instead, poor fossilization conditions and unexposed late Cretaceous rock layers mean they're either not preserved or hard to find.

Researchers have discovered a way to make tiny robots act like a material, mirroring embryonic tissue cells to adjust their structure on command.

May's full moon is the Flower Moon, rising May 12. It will also be a micromoon, appearing slightly smaller than usual.

The geology of the Cascadia subduction zone has largely staved off climate-related sea-level rise in the Pacific Northwest, but that could reverse in an instant.

The discovery of Eos, the closest known molecular cloud to Earth and one of the largest structures in the night sky, hints at the presence of many previously unseen clouds throughout the galaxy.
