Hubble Space Telescope
Stars galore 🌟 From Hubble's 24th year, this image shows the globular cluster M15. This spectacular swarm of stars is one of the densest globular clusters ever discovered, with very hot blue stars and cooler orange stars becoming more concentrated toward its bright core. Globular clusters are roughly spherical groupings of stars held together by their mutual gravitational attraction. M15 was also the first globular cluster known to host a planetary nebula – the gaseous shell of a dying star. We're sharing one outstanding image from each year of Hubble’s mission to celebrate its upcoming 35th birthday – counting down to a new series of anniversary images! Stay tuned for more, and get caught up at the link in our bio!
