Story summary

In July 2025, astronomers detected multiple gamma-ray bursts (GRBs) in a single day—the first in 50 years.
The bursts lasted far longer than typical GRBs, prompting questions about their origins.
A separate study detected millisecond pulsations in a GRB, suggesting newborn magnetars can drive these explosions.
Researchers use data from multiple telescopes to locate the extragalactic source and assess implications.
