Astronomers Have Detected an Intense And Mysteriously Low Frequency Radio Signal Coming From Space

By Fiona MacDonald

Astronomers have detected yet another mysterious and powerful fast radio burst hitting Earth from an unknown source in space.

If that’s not strange enough, this particular fast radio burst is incredibly low, in the 580 megahertz frequency range – nearly 200 MHz lower than any other fast radio burst we’ve picked up on before.

If you haven’t heard of fast radio bursts (FRBs), they’re some of the most explosive and mysterious events in the Universe.

They can generate as much energy as 500 million Suns in mere milliseconds, and there could be as many as one happening every second. The problem is, we still don’t know what’s causing them.

One of the signals we’ve detected has repeated, sending out multiple FRBs from the same location, and this has allowed us to pinpoint where in the Universe it’s coming from (spoiler: not our galaxy).
