Astronomers have detected mysterious radio waves coming from the center of the Milky Way, but so far they have no idea what's causing it, according to a new study published Tuesday in the Astrophysical Journal.
A team of scientists from across the world discovered the object using the CSIRO radio telescope in Western Australia.
The radio signal — named ASKAP J173608.2-321635 after its coordinates — was "unique" because it started out invisible, then it turned bright and faded away before reappearing again, said Tara Murphy, who is Wang's PhD supervisor and professor at the Sydney Institute for Astronomy and the School of Physics.
The scientists detected six radio signals from the source over nine months in 2020 and tried to find the object in visual light, but found nothing.
As scientists continue to keep an eye out for more clues, sources from other radio signals have been detected in recent months
In May, NASA traced the source of mysterious fast radio bursts sending signals to Earth.
