An intense blast of energy that was detected on Earth appears to have come from two colliding and collapsing stars, according to scientists.

Researchers looking through archival observations of gamma rays say they have found “oscillating” signals in two bursts of energy.

They were found in old data taken from an out-of-use experiment in orbit around Earth.
