Strange radio signals traced to outskirts of long-dead galaxy — and scientists aren't sure why
A dead galaxy shouldn't produce bursts of radio light. Yet this 11 billion-year-old one did — throwing scientists for a loop.
Most energetic neutrino ever found on Earth detected at the bottom of the Mediterranean Sea
Physicists have detected the highest-energy 'ghost particle' ever felt on Earth, with nearly 100 times more energy than any neutrino previously detected.
James Webb Space Telescope discovers one of the earliest 'truly gargantuan' supernovas ever seen
The James Webb Space Telescope has spotted one of the earliest and most distant supernovas, marking the death of a stellar monster 20 times the mass of the sun.
'Behemoth star' captured in spectacular close-up image — and it's on the brink of exploding
Astronomers have taken a superdetailed, zoomed-in photo of the Large Magellanic Cloud's "behemoth star." The stunning image, which is the first of its kind from outside the Milky Way, shows that the giant star is right on the edge of going supernova.
Scientists detect the most powerful cosmic rays ever — and their unknown source could be close to Earth
New research reports the most powerful cosmic rays ever detected. Because the rays lose energy as they travel through space, their detection at high energies means they are likely coming from sources relatively close to Earth.
Extremely rare 'failed supernova' may have erased a star from the night sky without a trace
An artist's rendering of a black hole
Accidental discovery of 1st-ever 'black hole triple' system challenges what we know about how singularities form
Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.
Supernova that lit up Earth's skies 843 years ago has a flowering 'zombie star' at its heart — and it's still exploding
A new animated map sheds light on the superhot "zombie star" at the heart of a nebula leftover from a distant supernova witnessed by astronomers in 1181. The remains of the stellar explosion are unusually wonky and are still exploding at a constant speed.
James Webb telescope watches ancient supernova replay 3 times — and confirms something is seriously wrong in our understanding of the universe
The James Webb Space Telescope has zoomed in on an ancient supernova, revealing fresh evidence that a crisis in cosmology called the Hubble tension isn't going anywhere soon.
