Story summary

Astronomers detected a cosmic explosion, ASKAP J005512-255834, an orphan afterglow of a gamma-ray burst.
The event released energy equivalent to a billion suns and faded as light interacted with surrounding gas.
The explosion originated in an irregular galaxy about 1.7 light-years away, likely in a dense star-forming region.
Researchers say the discovery could help identify similar echoes of explosions and advance understanding of cosmic events.
