Stars

An old galaxy reveals clusters of young stars that have formed in an unusually synchronized fashion, challenging the idea that star formation declines as galaxies age.

The neutron star 4U 1820-30 is one of the fastest spinning bodies in the universe, spinning at 716 times a second and erupting like an atomic bomb, NASA's NICER telescope has found.

The James Webb Space Telescope has discovered brown dwarfs at the heart of planet-forming disks in the Orion nebula. The discovery could help reveal if these "failed stars" can have planets.

To see the Crab Nebula for yourself, you'll have to wait until around midnight local daylight time, after it has sufficiently risen high enough above the east-northeast horizon.

A zombie star has defied expectations by surviving a supernova explosion that should have destroyed it. The undead white star's "grave" is marked by a cosmic dandelion.

The supergiant star Betelgeuse may have a companion star that pushes light-blocking dust out of the way, causing the irregular changes observed in the star's brightness.

The first and most famous "failed star" discovered by humanity isn't one brown dwarf, but two! The duo comprising Gliese 229B are so tightly bound they orbit each other in 12 days.

Using the Gaia space telescope, astronomers have observed 55 massive stars ejected from their home star cluster in the Large Magellanic Cloud at speeds equivalent to 80 times the speed of sound.

Using NASA's exoplanet-hunting spacecraft, TESS, astronomers and citizen scientists have discovered a record-breaking system of three tightly bound stars that could fit between the sun and Mercury.
