"Unraveling the Mystery of Enormous Cosmic Smoke Rings in Space"

Astronomers have identified the origin of enormous "odd radio circles" (ORCs) as outflowing galactic winds from exploding stars in starburst galaxies, which occur when two large galaxies collide, pushing gas into a small region and causing intense bursts of star formation. These ORCs, measuring about a million light-years across, were initially thought to be imaging artifacts but have been confirmed as a new class of astronomical object only visible in the radio spectrum. Computer simulations and spectrograph data support the theory that ORCs are formed by powerful outflowing galactic winds, providing a rare opportunity to study galactic winds through radio data and spectrometry.
