Astrophysicist Natasha Hurley-Walker marked the position of the mysterious object in the Milky Way with a little sun symbol
The object, first spotted by a university student working on his undergraduate thesis, releases a huge burst of radio energy three times every hour.
The pulse comes “every 18.18 minutes, like clockwork,” said astrophysicist Natasha Hurley-Walker, who led the investigation after the student’s discovery, using a telescope in the Western Australian outback known as the Murchison Widefield Array.
While there are other objects in the universe that switch on and off – such as pulsars – Ms Hurley-Walker said 18.18 minutes is a frequency that has never been observed before.
Finding this object was “kind of spooky for an astronomer,” she said, “because there’s nothing known in the sky that does that.”
