A new Odd Radio Circle (ORC) appears to span a million light years, and contains a clue that could explain these ghostly structures.
After 57 years of service to the astronomical community, the Arecibo Observatory collapsed on Tuesday, sparking widespread grief.
Scientists believe they have likely discovered a new and unexplained class of space object: the Odd Radio Circle, or ORC.
A newly funded concept envisions a kilometer-wide radio telescope built inside a crater on the far side of the Moon. Whoa.
A supermassive black hole's eruption blasted for hundreds of millions of years, making it the biggest explosion ever detected since the Big Bang.
Scientists are building enormous new radio arrays capable of hearing leaks from alien broadcasts, if they exist.
Molecular oxygen is a key component of the air humans breathe, and now astronomers have spotted it a half-billion light years away. But don't hold your breath for quasar whippets.
Only three such blasts have ever been detected by scientists, making them an extremely rare and weird phenomenon that can teach us about how stars form.
The faint, 12-billion-year-old signal would lead scientists to the very first stars and illuminate the origins of the modern universe, dark matter, and, well, everything.
“This is the big breakthrough that the field has been waiting for since astronomers discovered fast radio bursts in 2007.”
"This is one of the most extraordinary black hole systems I've ever come across.”
Mission leads are trying to reestablish contact with the Spektr-R satellite, which carries a 10-meter wide radio dish.
