Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.

Some of the earliest galaxies found with JWST are also the brightest. That's a problem for our ideas about the universe.

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.

The Dark Energy Camera imaged the Rosette Nebula, capturing a kaleidoscope of color created by the star cluster born within it.

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.

Astronomers at the European Southern Observatory have released the largest infrared map of the Milky Way ever. The enormous dataset contains millions of new objects, and the researchers expect to scour it for discoveries for years to come.

Strange, ultraheavy stars that are rich in barium grow massive by cannibalizing their companions, scientists discover after finally catching these stellar leeches in the act.

A new image from the James Webb Space Telescope shows Arp 107, home to two merging galaxies, with two bright cores and a "bridge" of dust and gas forming a cosmic smiley face.
