The John J. McCarthy Observatory in New Milford will hold its next “Second Saturday Stars” program, “NASA’s Great Space Observatory Program,” Feb. 9 from 7 to 9 p.m.

The program at the observatory, located behind New Milford High School on Route 7 South, will address the Hubble space telescope. The plans for its stemmed from a visionary scientist, Lyman Spitzer, starting in 1946, 11 years before Sputnik orbited the earth.

The idea was to study the heavens from infrared to gamma ray light, outside the confines of earth’s atmosphere.

Out of this came the Hubble, the Compton, the Chandra and the Spitzer Observatories.

The program will highlight the successes, and focus on how the observatories have partnered to study the cosmos, and what new space observatories have been deployed and what is planned in coming years.
