ABDNHA 41st Annual Desert Lecture Series



Dennis Mammana

Astronomer, Writer & Sky Photographer

On Friday, April 12, Dennis Mammana presents stunning images of the Earth’s celestial attractions by an array of international photographers. The eternally peaceful night sky looks the same above the symbols of all nations and regions, attesting to the truly unified nature of Earth as a planet, rather than an amalgam of human-designated territories. As the world’s second official International Dark-Sky Community, Borrego Springs is part of an international effort to preserve the view of the dark night sky for now and future generations. Don’t miss this beautiful and inspirational program. At the Borrego Springs Performing Arts Center. Seating is limited and on a first-come, first-served basis. Arrive early for best seating.

Program: "From Panels to Power: How Solar Energy Works"

Presented by Paul Zavesoff, Asset Manager, NRG Borrego Solar Project

First attend the lecture on solar power and then go on the tour

We jump from the dark skies of night to the opposite side of day and to the latest technology that permits us to generate electrical power from the sun, the star that powers all life on Earth. Learn how solar panels produce electricity, what goes into a modern solar plant—such as the Borrego Solar Project—and what the future holds, and how the sunshine falling on Borrego will ultimately be delivered to homes and businesses in the form of electricity. The illustrated program takes place at the ABDNHA Borrego Desert Nature Center, in the ABDNHA Library. No charge. Space limited, call for reservations, 760-767-3098. If you are holding a reservation, but cannot attend, please call ahead so that someone else may have your place.
