Stars

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

"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."

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.

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

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

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.
