Catching Core-Collapse Supernovae Before They Happen

What happens right before a massive star explodes violently in a supernova explosion? A recent study predicts an influx of pre-explosion observations will arise after the Vera C. Rubin Observatory turns on this summer, unlocking the mysteries surrounding massive stars’ ends.

Jupiter’s Atmosphere Holds Steady

Astronomers knew that Jupiter’s upper atmosphere could be strangely warm, but only now do they have global maps showing just where those hot spots are and how long they last.
