Scientists have detected a “strange and persistent” radio signal that sounds like a heartbeat in a distant galaxy.
Scientists have detected a “strange and persistent” radio signal from a distant galaxy that resembles a heartbeat.
Astronomers at the Massachusetts Institute of Technology and elsewhere have detected the signal, which is classified as a fast radio burst, or FRB, which lasted longer.
The signal repeated over 0.02 seconds in a clear pattern, almost like a heartbeat.
Daniele Michilli, a postdoc at MIT’s Kavli Institute for Astrophysics and Space Research said it was unusual.
Not only is it long-lasting about three seconds, but there is a peak at some point that is very precise, bringing out every fraction of a second – boom, boom, progress – like a heart attack.
This is the first time the signal itself is periodic.” Daniel said.
The Canadian Hydrogen Intensity Mapping Experiment, or CHIME, is an interferometric radio telescope that continues to observe the sky and is sensitive to fast radio bursts.
Most FRBs are single-ended and last a few milliseconds before ending. But a signal that occurs every 16 days has recently been discovered, although the signal is more random.
The first FRB was discovered in 2007 and hundreds of similar radio flashes have been detected in space since.
