Say Hello to NGC 6441

A crowded cluster of over a million stars packs together at the center of this image of the star cluster NGC 6441. These stars shine in white, red, blue, and yellowish hues, and grow more sporadic at the image’s edges, all glittering against a black backdrop of space. Credit: ESA/Hubble & NASA, G. PiottoALT

Location: In the Scorpius constellation

Distance from Earth: About 44,000 light-years

Object type: Globular star cluster

Discovered by: James Dunlop in 1826

Each tiny point of light in this image is its own star - and there are more than a million of them! This stunning image captured by the Hubble Telescope depicts NGC 6441, a globular cluster that weighs about 1.6 million times the mass of our Sun. Globular clusters like NGC 6441 are groups of old stars held together by their mutual gravitational attraction, appearing nearly spherical in shape due to the density of stars that comprises them. This particular cluster is one of the most massive and luminous in our Milky Way Galaxy. It is also home to a planetary nebula and four pulsars (rotating neutron stars that emit beams of radiation at steady intervals, detected when the beams are aimed at Earth).

Right now, the Hubble Space Telescope is delving into its #StarrySights campaign! Find more star cluster content and spectacular new images by following along on Hubble’s Twitter, Facebook, and Instagram.
