MILKY WAY GALAXY (WUTR/WFXV/WPNY) – Astronomers at the University of Sydney in Australia have discovered unusual signals coming from the center of the Milky Way. The source was detected six times between 2020 January and 2020 September.
“The strangest property of this new signal is that it has a very high polarization. This means its light oscillates in only one direction, but that direction rotates with time,” said Ziteng Wang, the lead author of this new study at the University of Sydney. “The brightness of the object also varies dramatically, by a factor of 100, and the signal switches on and off apparently at random. We’ve never seen anything like it.”
He explained further that the object started out invisible, became bright, faded away, and then reappeared. Very unusual behavior that could suggest a new class of stellar objects.
When the astronomers tried to find the object in visual light, they found nothing. The signal did eventually return, but they found that its behavior was dramatically different. It disappeared in a single day, even though it had lasted for weeks in previous observations. Mr. Wang and his team plan to keep a close eye on this object to look for more clues on what it might be.
