Deep Space Signal Repeats

A telescope in Canada received mysterious signals coming from 1.5 billion light years away. The precise cause of the blasts of radio waves is unknown.

They may be exploding stars, stars with strong magnetic fields, stars merging together and – among a minority of observers – some form of alien intelligence.

Canada's new radio telescope, CHIME

CHIME EXPERIMENTCanada’s new radio telescope is made up of four 100-metre-long antennas, which scan the entire northern sky each day.

What did the telescope find?

Canada’s CHIME radio telescope detected 13 fast radio bursts, known as FRBs. It also heard a very unusual repeating signal, coming from the same source about 1.5 billion light years away.

This is only the second time that fast radio bursts have been detected.

Studying FRBs is difficult because they are so rare. Therefore, the signals have remained a mystery, with little evidence at all of where they might be coming from.

The flashes only last for a millisecond and has the same amount of energy as the sun produces in a year.

Scientists are planning on studying the radio waves and hope that this new discovery will allow them to answer the mystery.
