Strange and intense blasts of radio energy were monitored within our own galaxy, say astronomers in a new study published in the journal Nature.

Specifically, the detected signals are fast radio bursts (FRBs) — which last only a small fraction of a second but can possess more power than the sun itself. Despite the intensity of FRBs, their causal origin remains largely unknown, reports The Independent.

However, in the new study, astronomers observed a fast radio burst in our own Milky Way galaxy — for the first time. This is closer than any FRB previously detected, and might help astronomers understand from where and how they come to exist.
