But this new one, dubbed GRB 250702B, blows everything we know about these fearsome blasts out the water. For starters, it lasted a staggering seven hours, which is vastly longer than they typically do. And it also appeared to repeat several times over its run, which shouldn't be possible. A GRB is produced by the total obliteration of a star, so how could the same source emit multiple blasts?

Light echoes occur when a massive star detonates, creating a flash of light that expands rapidly. This light defines a spherical shell around the explosion.

The enormous interstellar object, now officially dubbed 3I/ATLAS, is already speeding through the solar system at 41 miles per second, or 150,000 miles per hour. This has sparked speculation that 3I/ATLAS's intense brightness might not have a natural explanation.

The Andromeda galaxy lies just beyond our galaxy, about 2.5 million light-years beyond, and they are gravitationally bound, existing in a long-term dance of doom.

It used to appear destined to merge with Andromeda forming a colossal "Milkomeda." Now, there is a chance that we could avoid this fate entirely.

These are by far the most detailed observations of this kind, showing features not previously observed, and it's not quite clear what they are.

Masters states that observing the cosmos has equipped him to manage data intricacies at Virgin Atlantic, emphasizing the importance of stripping noise to glean insights.

"When you have a whole bunch of things moving together like that in a swarm, a natural question is going to be, do they sometimes bump into each other?" Lacki told New Scientist. "At their orbital speeds, that can be disastrous."
