What happens when neutrinos swap identities inside a supernova?
Identity-fluid particles may carry some energy out, leading to direct collapse. Our basic understanding of core-collapse supernovae hasn’t changed in […]
Scientists find closest star to the Milky Way’s central black hole
Over time, the orbit of the newly discovered star will depend on whether Sgr A* is spinning. Credit: ESO/GRAVITY/L. Calçada […]
The world’s biggest solar telescope caught vortexes on the Sun’s surface
We expected them to be there, but they had previously been too small to see. Wherever two fluids slide past […]
A Jupiter-size planet that escaped its star’s death
It’s unclear how the planet avoided its star’s bloated red giant stage. WD 1856 b is the only confirmed case […]
Planet orbits so close to its star that their magnetic fields connect
The second issue was that in some observations, there were no periodic signals at all. Because we have enough archival […]
A bold satellite rescue mission came together in record time, but will it work?
“I consider this a success already, just from the fact that we’re even going to try this.” The Link spacecraft […]
“Little red dot” in early Universe is a naked supermassive black hole
These models placed the black hole’s mass at about 50 million times that of the Sun, which is in line […]
“I’ll buy 10 of those”—NASA science chief yearns for mass-produced satellites
“How in the hell do I get more science into space? That is my goal.” Saturn’s moon Enceladus peeks over […]
