Just Announced: Strange Signals From the Galaxy’s Center

Astronomers: “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.”

“Strange radio waves emerge from direction of the galactic centre”? Yes, it sounds like the opening of a trailer for a sci-fi film. But it is actually a media release from last week from the University of Sydney in Australia: Astronomers have discovered unusual signals coming from the direction of the Milky Way’s centre. The radio waves fit no currently understood pattern of variable radio source and could suggest a new class of stellar object. “The strangest property of this new signal is that it is has a very high polarisation. This means its light oscillates in only one direction, but that direction rotates with time,” said Ziteng Wang, lead author of the new study and a PhD student in Read More ›
