Hubble Captures Globular Cluster NGC 6441

The Hubble Space Telescope has delivered another outstanding image. This one is of NGC 6441, a massive globular cluster in the constellation Scorpius. It’s one of the most massive ones in the Milky Way, and the stars in it have a combined mass of 1.6 million solar masses.

NGC 6441 is a gorgeous visual spectacle. It’s also of great scientific interest; it hosts four pulsars, an abnormally high number of variable stars, and has a rather high metallicity for a globular cluster. And it’s host to several Type II Cepheid stars, which is unusual for a cluster with high metallicity.
