NASA’s DART Mission Changed Orbit of Asteroid Didymos Around Sun

New research reveals that when NASA’s DART (Double Asteroid Redirection Test) spacecraft intentionally impacted the asteroid moonlet Dimorphos in September 2022, it didn’t just change the motion of Dimorphos around its larger companion, Didymos; the crash also shifted the orbit of both asteroids around the Sun.

Gamma-ray Bursts: Harvesting Knowledge From the Universe’s Most Powerful Explosions

The most powerful events in the known universe – gamma-ray bursts (GRBs) – are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our Sun. Now thought to announce the births of new black holes, they were discovered by accident. The backstory […]
