The John J. McCarthy Observatory in New Milford will hold its next Second Saturday Stars event April 11 from 8 to 10 p.m.

The topic of the program at the observatory located behind New Milford High School on Route 7 South will be "The State of the Earth."

In a departure from the usual Second Saturday Stars programs of education and entertainment, this event will serve as a call to action to help protect Earth's biosphere.
