A shockwave erupts from the star's surface, and for a brief moment, a blinding flash of ultraviolet and X-rays is born. This very event, named EP260321a, was spotted by the Einstein space telescope in March 2026. The light took about 450 million years to reach Earth.

Predicted by Albert Einstein, gravitational waves are like beacons in the dark ocean of space. They flare up when black holes collide, sending ripples through the fabric of the Universe.
