Astronomers have observed a gamma-ray burst (GRB) that repeated multiple times over a day, a phenomenon never seen before, and located it in another galaxy using the Very Large Telescope. This GRB’s unusual duration and repetition challenge existing models of such cosmic explosions.

Why it matters: This discovery reveals a new type of gamma-ray burst that defies current understanding of these powerful cosmic events.

The big picture: GRBs typically last seconds to minutes and never repeat, but this day-long, repeating burst suggests unknown astrophysical processes.

The stakes: Understanding this event could uncover new physics related to star collapse or black hole interactions, possibly involving intermediate-mass black holes.

Commenters say: Opinions range from excitement over the astronomical breakthrough to humorous speculation about alien involvement, highlighting curiosity and mystery surrounding the event.
