New Hubble Messier images unveiled every day!
Every year, stargazers convene for the “Messier Marathon” – a challenge to observe as many cosmic objects from the Messier catalog as possible in a single night! This catalog was compiled in the 1700s by French astronomer Charles Messier, and features several ideal targets for backyard astronomers. No telescope? No problem! Stargaze from your screen with Hubble, as a suite of new Messier images are unveiled from March 14-21.
Messier 10

History
Charles Messier
Charles Messier (1730–1817) was a French astronomer best known for his “Catalog of Nebulae and Star Clusters.”
An avid comet-hunter, Messier compiled a catalog of deep-sky objects in order to help prevent other comet enthusiasts from wasting their time studying objects that were not comets.
