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.”

For the first time, a much younger version of the Sun 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. Winds from the star’s surface are blowing up the bubble and filling it with hot gas […]
Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, 2025, where it was detected by the All-Sky Automated Survey for Supernovae. Astronomers immediately turned their resources to this new supernova, designated 2025pht, […]
Astronomers suspect the heart of the Milky Way may be hiding a big secret: a rapidly spinning, highly magnetic, neutron star-powered pulsar.
