Welcome to Hubble's Messier Marathon 2026! This annual event encourages astronomers to target cosmic objects from the Messier catalog, compiled by French astronomer Charles Messier in the 1700s. We're sharing new Hubble images of Messier objects through next weekend ⬇️

First up: Messier 10! M10 is a globular cluster, which is a roughly spherical grouping of stars held together by their mutual gravity. This cluster is about 15,000 light-years away, and can be found in the constellation Ophiuchus. go.nasa.gov/418BVff
