Astronomers discover the most powerful and distant cosmic ring ever seen
SMRTR summary
Astronomers have discovered the most distant and powerful "odd radio circle" (ORC) ever found, located nearly 10 billion light-years away when the universe was half its current age, using citizen scientists and Europe's most sensitive radio telescope. These mysterious ring-shaped structures, only discovered six years ago, may form from superwind outflows from galaxies rather than colliding black holes as previously thought.
