How many Earth-like planets are in our galaxy? Scientists have asked that question for hundreds of years. Thanks to data from the Kepler spacecraft, we're starting to find the answer.

To learn the latest about the search for habitable worlds, tune in to a live webcast of "We Are Not Alone," the next Observatory Night at the Harvard-Smithsonian Center for Astrophysics (CfA). Researcher Courtney Dressing will present new evidence that Earth-like planets are more prevalent than we thought and should be located right next door!

If you miss the live broadcast, this Observatory Night talk will be posted to the CfA YouTube channel a week after the event:


Observatory Nights are held on the third Thursday of every month during the academic year. These 40-minute talks cover a variety of timely astronomical topics. Observatory Nights take place at Phillips Auditorium, 60 Garden Street, Cambridge, Mass.

Then-CfA director Harlow Shapley founded the "Observatory Nights" program in 1930 in order to give the public an opportunity to learn about astronomers' latest discoveries and to view the cosmos through telescopes. More than 80 years later, Shapley's prescience is confirmed and Observatory Nights are still going strong, reaching ever-wider audiences online.

Headquartered in Cambridge, Mass., the Harvard-Smithsonian Center for Astrophysics (CfA) is a joint collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory. CfA scientists, organized into six research divisions, study the origin, evolution and ultimate fate of the universe.
