According to a research paper published in Nature, astronomers detected a “really weird” object 4,000 lightyears distant from Earth. Every other minute, the object vanishes from view and produces a massive burst of radio waves three times an hour.
Scientists refer to space objects that “turn” on and off in the night sky as “transients”.
“When studying transients, you’re watching the death of a massive star or the activity of the remnants it leaves behind,” said Dr. Gemma Anderson, an ICRAR-Curtin astrophysicist and co-author of the work.
“It was kind of spooky for an astronomer because there’s nothing known in the sky that does that,” said astrophysicist Dr. Natasha Hurley-Walker, who headed the research team. “And it’s really close to us – about 4000 lightyears distant. It’s there in our galaxy’s backyard.”
“It’s a type of slowly spinning neutron star that has been predicted to exist theoretically,” Hurley-Walker explained. “However, no one anticipated to immediately discover one like this since they were not thought to be that brilliant. It converts magnetic energy to radio waves considerably more efficiently than anything else we’ve seen previously.”
Astronomers believe it is a rare sort of neutron star or a collapsing white dwarf, but they need to examine it again to establish if it is a fluke or a new type of space object.
