Explainer: Calculating a star’s age

Scientists can figure out a star's mass or composition pretty easily. Determining how old that star is, however, is a lot harder.

Tech

Easy for you, tough for a robot

Robots still can’t do many things that we find easy. Can engineers reduce how klutzy robots are and boost their common sense?
