While scanning the skies for cosmic radio signals, astronomers found a mysterious celestial object never observed before that releases bursts of energy three times per hour.
“This object was appearing and disappearing over a few hours during our observations,” said Natasha Hurley-Walker, an astrophysicist at Curtin University and the International Centre for Radio Astronomy Research in Australia. “That was completely unexpected. It was kind of spooky for an astronomer because there’s nothing known in the sky that does that.”
