Researchers in world-regionssaid they located a “spooky” item about 4,000 light-years away that mysteriously becomes one of the brightest objects in the sky for about one minute every 20 minutes, according to a report.
Natasha Hurley-Walker, an astrophysicist from Australia’s Curtin University, International Center for Radio Astronomy Research, said observing its odd bursts of radiation was a bit spooky because “there’s nothing known in the sky that does that,” Bloomberg reported.

Phys.org reported that there are theories about what the object could be. The main theory is that the object is a neutron star or white dwarf, which the website identified as “collapsed cores of stars—with an ultra-powerful magnetic field.”

Hurley-Walker also pointed out that the object is 4,000 light-years away, which may sound like a long haul but is seen by astrophysicists as essentially akin to being in our own “galactic backyard.” There are other known objects that flash in space, but this frequency has not been seen.
She said there is a theory about a “slowly spinning neutron star.”
“But nobody expected to directly detect one like this because we didn’t expect them to be so bright. Somehow it’s converting magnetic energy to radio waves much more effectively than anything we’ve seen before,” she said.
