An global staff of astronomers has detected “unusual signals” coming from the heart of the Milky Way galaxy and suspect a “new class of stellar object” could be the resource.
Objects in the cosmos these kinds of as planets, comets, big clouds of fuel and stars have modifying magnetic fields and make radio waves that can be picked up on Earth by substantial radio telescope arrays positioned all all-around the world.
But a new research published this week in the Astrophysical Journal details the discovery of radio waves that look to be compared with anything the experts have studied before.
“At 1st we assumed it could be a pulsar — a quite dense type of spinning lifeless star — or else a kind of star that emits huge solar flares. But the signals from this new resource really don’t match what we anticipate from these sorts of celestial objects,” Ziteng Wang, direct writer of the review and PhD university student at the School of Physics at the University of Sydney, stated in a assertion.

“The strangest house of this new sign is that it has a really significant polarization. This usually means its light-weight oscillates in only one route, but that direction rotates with time,” Wang said.
“The brightness of the object also differs drastically, by a issue of 100, and the signal switches on and off seemingly at random. We’ve never seen anything like it,” he additional.
The radio waves were being observed working with the ASKAP radio telescope situated in the desert of Western Australia, with observe-up observations carried out by the South African Radio Astronomy Observatory’s MeerKat telescope.
Signals from the item, dubbed ASKAP J173608.2-321635 due to the fact of its coordinates, were picked up 6 periods more than nine months previous year. Scientists said they attempted to discover the object in visual light, but were unsuccessful.
Astronomers say they system to continue to keep monitoring the object for clues as to what it could be, and they hope extra sophisticated telescopes set to occur on the internet in the coming many years can assistance clear up the mystery.
