Discover the mysteries of our universe in this outdoor presentation!

A large portion of the universe cannot be seen by the human eye, or even with very large optical telescopes. But radio and gravity waves can be detected, helping us unravel the mysteries of space and time.

The presenter, Steven Bellavia, is currently the principal mechanical engineer for the camera on the Vera Rubin telescope (formerly called the Large Synoptic Survey Telescope, LSST) at Brookhaven National Laboratory, where he has worked since 1992. Prior to that, Steve was doing research and engineering for the Relativistic Heavy Ion Collider and the NASA Space Radiation Laboratory. As an aerospace engineer for Grumman Aerospace with the Thermodynamics Group of the Space Division he played a key role in developing a nuclear rocket engine and with the design, fabrication, and analysis of a micro-gravity liquid droplet radiator that flew on Space Shuttle mission STS-029.

Following the presentation, Observatory staff will provide guided tours of the night sky (weather permitting) through the many telescopes on site, including the apochromatic Zerochromat telescope in our historic observation dome.

$5 Adult, $3 Children Under 16, Observatory Members FREE. Your donations make it possible to offer programs like these and are greatly appreciated. Due to limited space, registration is strongly encouraged.

A rain date for this outdoor program is scheduled for August 20 at 8:30pm. Please bring a blanket or chair to enjoy this outdoor presentation.

The event is finished.
