Public Observatory Event - DOUBLE HEADER

Come see Messier 13 at 10pm, sometimes called the Great Globular Cluster in Hercules, or the Hercules Globular Cluster, is a globular cluster of about 300,000 stars.

BUT WAIT, THERE’S MORE: Also, at midnight, see the Ring Nebula (Messier 57), a planetary nebula in the northern constellation of Lyra. Such objects are formed when a shell of ionized gas is expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution.

Visitors’ Nights at the Observatory are free of charge and no reservations are required. Each observing session is open-ended. Children are welcome to attend but must be accompanied by an adult. All visitors must be able to ascend a short set of stairs to view the object through the telescope.
