00:45 A bright satellite is concerning researchersSatellites reflect sunlight down to Earth, and some do so with such intensity it risks obscuring astronomers' observations from ground-based telescopes. A paper in Nature suggests that the telecommunications satellite called BlueWalker 3 at times outshines most stars visible from Earth. Astronomers worry about the increasing number of such bright satellites making astronomy more difficult, and so the team suggest that future launches should undergo impact assessments.

Trilobites are a group of extinct marine arthropods distantly related to animals like crabs and spiders. Although found throughout the fossil record, little is known about the lives of this diverse group of animals. Now, a team has used powerful x-rays to peer inside a trilobite fossil and uncovered the contents of its last meal, over 400-million-years ago. This animal appears to have been an unfussy scavenger, gorging itself on a variety of small, shelled animals.
