Prepare to be amazed as we delve into a cosmic mystery that will leave you in awe! The universe has unveiled a breathtaking secret, and it's unlike anything we've ever seen before.
Astronomers, with eyes wide in wonder, have stumbled upon a distant galaxy adorned with two massive, intersecting rings of radio light, each spanning an incredible 300,000 light-years. This extraordinary find, courtesy of citizen scientists in Mumbai, is none other than an 'Odd Radio Circle' (ORC) - a term that might sound whimsical but is very real.
These enigmatic circles, first discovered only six years ago, continue to puzzle scientists. Are they shockwaves from colliding black holes or galaxies? With most ORCs being 10 to 20 times larger than our very own Milky Way, their origin story remains shrouded in mystery.
The newly discovered ORC, named RAD J131346.9+500320, is a true marvel. It's the most distant and powerful ORC ever found, offering a glimpse into the universe's past when it was just half its current age of 13.8 billion years. What's even more extraordinary is that it boasts two overlapping circles, a phenomenon so rare it's only been observed once before.
"ORCs are truly bizarre and breathtaking cosmic structures," says Ananda Hota, founder of the citizen science program, "and they could hold the key to understanding how galaxies and black holes evolve together."

What's unique about this discovery is that it's the first ORC found through citizen-assisted science and the first identified using LOFAR, a network of antennas across Europe. ORCs are elusive, only detectable by radio telescopes.
But here's where it gets controversial... The authors suggest that these rings might be the result of powerful winds emanating from certain galaxies, shaping the distant space around them. An animation, created by the program, depicts this rare double-ring ORC expanding after an explosive event in the central galaxy.
The program also uncovered two other intriguing examples. In RAD J122622.6+640622, astronomers observed a galaxy nearly 3 million light-years across, with one of its core jets forming a sudden curve, creating a ring of radio light approximately 100,000 light-years wide.
In RAD J142004.0+621715, the galaxy, stretching 1.4 million light-years, displayed a similar ring at the tip of one of its jets, accompanied by another narrow jet on the opposite side of the host galaxy.
Scientists believe these strange cosmic objects reveal that galaxies have the power to influence their surroundings in ways we never imagined.
"ORCs and radio rings are not mere oddities; they are part of a larger family of exotic plasma structures shaped by black hole jets and winds," explains Pratik Dabhade, a co-author from the National Centre for Nuclear Research in Poland.
This discovery challenges our understanding of the cosmos and leaves us with more questions than answers. What do you think? Could these rings be the result of powerful galactic winds, or is there another explanation? We'd love to hear your thoughts in the comments below!
