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.

An organic molecule called methanimine was found scattered throughout a dense clump of gas and dust 554 light-years away.

Astronomers have spotted a heart in the cosmos — not Cupid’s doing, but a dying star shedding its layers — just in time for Valentine’s Day.

Astronomers witnessed a star emitting as much energy in mere moments as our sun puts out in a few months. The dramatic observation gives a direct look into the brutal physics of these stellar events.

“We studied the last several orbits before the merger, when the entwined magnetic fields undergo rapid and dramatic changes, and modeled potentially observable high-energy signals.”

When young stars mix with neutron stars, things get messy.
NASA has released its monthly skywatching update on what to look out for over the coming weeks, and you can probably guess which event tops the list. That’s right: the Artemis II mission. NASA is about to launch a crew on a voyage around the moon in wh…
“Stars like the sun don’t just stop shining for no reason.”
