The Missouri S&T Observatory will open its doors at 10:30 p.m. for viewing star cluster Messier 3 through the observatory’s 16-inch diameter telescope on Thursday, March 22. The sky must be clear for observing, and the session length will vary.
Messier 3 was discovered by Charles Messier in 1764, and resolved into stars by William Herschel around 1784. It has since become one of the best-studied globular clusters.
