Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.
…
Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth’s magnetosphere is the “magic trick” behind superbright supernovas.

For the first time, a young, Sun-like star has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star in this image released on Feb. 23, 2026. Winds from the star’s surface are blowing up the bubble and […]
“TIC 120362137 is currently the most compact known 3+1-type quadruple star system.”
There’s a whole slew of objects that astronomers aren’t sure whether to classify as “failed stars” or “overgrown planets.”
