Stars

"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.

"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."
