Moraine Valley Community College is hosting an open viewing at its telescope observatory on Saturday, Oct. 21, 6:15 p.m., on campus, 9000 W. College Parkway, Palos Hills.

The college has a 6.5-foot Newtonian reflecting telescope built by a retired professor and housed in a dome on the G. Jack Bradley Observation Deck. The viewing will take place on the deck, on the west side of the college’s Nature Study Area, off Kean Avenue near 107th Street. Observers can park in lots east of Building P or in the west section of the Building D parking lot and then walk on the path to the observation deck. Children must be accompanied by an adult or guardian.

Visitors should dress for the weather and can bring their own binoculars or telescopes. The viewing will be canceled if it is cloudy, rainy or there are high winds. Occasionally, the International Space Station passes into view. This night should include good views of Jupiter, Neptune, Uranus and Saturn.
