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.

Betelgeuse, one of the brightest stars in the sky, may have a secret sunlike companion that drives the star’s mysterious six-year-long "heartbeat," new research suggests.

The Andromeda Galaxy, the Milky Way's closest galactic neighbor, glows brightly in a new Hubble Space Telescope image with swathes of ionized gas that fuel star formation.

These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.

The Very Large Telescope in northern Chile imaged a "super-Jupiter" exoplanet called 2M1207b, precisely 20 years ago this week. This was the first direct visual confirmation of a world beyond our solar system.
