Stars

"It's possible we’re swimming in a whole sea of these objects that are really faint and hard to see."

A "guest star," briefly seen in 1181, was created by colliding dead stars.

A Navy research team intern is part of a group of astronomers who have discovered a rapidly spinning neutron star, or "pulsar," in a dense cluster of stars around 10 light-years away.

The 'heartbeats' of rapidly spinning neutron stars are usually highly regular, but occasionally, the spin of these dead star pulsars 'glitches.' Now, a 'twisted' model could explain this mystery.

Binary star system T Coronae Borealis (T CrB) is about to go nova any day now. The recurrent nova explodes approximately every 79 or 80 years.

To celebrate its 25th anniversary, the Gemini North telescope team has released a stunning image of starburst galaxy NGC 4449, which is ablaze with intense star birth as it devours smaller galaxies.

Using the ALMA radio telescope array, astronomers have investigated the disks of gas and dust around young binary stars to better understand how these systems procure planets.

Neutron stars smashing together may create and trap ghost particles called neutrinos, and this discovery could help us better understand how elements like gold are forged.

Neutron stars with surface temperatures millions of degrees cooler than expected rule out a swathe of possible models to describe the physics of such objects.

A young star that astronomers have studied for decades has been found to be part of a duo, encircled by a disk of material within which planets may have just begun coalescing.
