A unique NASA satellite is falling out of orbit—this team is trying to rescue it
Katalyst Space Technologies must launch the Swift rescue mission by this summer. NASA’s Swift observatory is unwrapped after shipment to […]
Magnetars drag spacetime to power superluminous supernovae
Frame-dragging may explain an odd pattern seen in the brightest supernovae. Some of the most extreme explosions in the universe […]
This black hole “burps” with Death Star energy
When AT2018hyz, aka “Jetty,” was first discovered, radio telescopes didn’t detect any signatures of an outflow emission of material within the […]
NASA launches new mission to get the most out of the James Webb Space Telescope
“It was not recognized how serious a problem that is until… about 2017 or 2018.” The Pandora observatory, seen here […]
Runaway black hole mergers may have built supermassive black holes
The researchers used cosmological simulations to recreate the first 700 million years of cosmic history, focusing on the formation of […]
Next-generation black hole imaging may help us understand gravity better

There could be “dark main sequence” stars at the galactic center
Dark matter particle and antiparticle collisions could make some stars immortal. For a star, its initial mass is everything. It […]
Merger of two massive black holes is one for the record books
Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two […]
