Exploding stars emit powerful bursts of energy – I’m leading a citizen scientist project to catalog and understand these bright flashes

Gamma ray bursts happen when neutron stars collide or when giant stars explode into black holes, releasing jets of super-energetic photons that look like a narrow beam of a flashlight.

This article was originally published in dialogue. The publication contributed this article to Space.com Expert Voices: Columns and Insights. Amy Lane is an assistant professor of physics at the University …
