A mass stellar migration billions of years ago may have helped life get started on Earth

Our sun and a host of “solar twins” may have migrated away from the core of the Milky Way galaxy together long ago, potentially making the solar system more hospitable to life.

A new image captured by the Very Large Telescope reveals stars and gas orbiting the “invisible giant” at the heart of our galaxy.

Blowing Stellar Bubbles
Blowing Stellar Bubbles

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 […]

This record-breaking quadruple star system is so jam-packed it could fit between Jupiter and our sun

“TIC 120362137 is currently the most compact known 3+1-type quadruple star system.”

Could these weird stars just be overgrown planets?

There’s a whole slew of objects that astronomers aren’t sure whether to classify as “failed stars” or “overgrown planets.”

Astronomers just watched a star 1,540 times the size of our sun transform into a hypergiant. Will it go supernova?

One of our universe’s biggest stars has dramatically turned into a rare, yellow ‘hypergiant’ star, and astronomers aren’t sure when it will go supernova.

NASA space telescope gets 1st clear X-ray image of sun-like star blowing a bubble

The observations offer a rare glimpse into our solar system’s early history.

Two stars carve egg-shaped nebula | Space photo of the day Feb. 24, 2026

Two aging stars in the binary system AFGL 4106 sculpt a glowing, egg-shaped nebula as they approach the end of their lives.

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 […]

NASA’s Webb Telescope Locates Former Star That Exploded as Supernova
NASA’s Webb Telescope Locates Former Star That Exploded as Supernova

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, […]
