Come at 6:30 p.m. for a FREE showing of Cosmic Voyage in the Lockheed Martin IMAX Theater.
A generator in space, 150 million km away, heats the Earth, structures its atmosphere, and organizes the surrounding space environment. The Sun's energy output changes continually, with myriad Earthly consequences. How much of recent surface warming and atmospheric ozone depletion are solar- rather than human-induced? Will a solar storm be deadly for space instruments and astronauts alike? How might solar effects on navigation, communication, and Earth-orbiting objects compromise security and commerce?
Dr. Judith Lean will discuss changes in solar output and the impact on the Earth, technology, and society.
Lean is a solar physicist with the E.O. Hulburt Center for Space Research at the U.S. Naval Research Laboratory in Washington, D.C., and specializes in the study of the variability of solar radiation.
This lecture is free, but tickets are required. There will be free pre-lecture activities starting at 6:00 p.m. Check back often for more information.
The series continues through June.
