Planet George? Dr. Bruce Betts has this week's Random Space Fact!
This throwback is long, but worth the watch! Hear the 1988 Mars Declaration from The Planetary Society as read by Carl Sagan, Gene Roddenbery, Isaac Asimov, Ann Druyan, Thomas Paine, Louis Friedman, Bruce Murray, Steve Allen, and Diane Ackerman just to name a few. Enjoy this lengthy piece of our history!
Lecture 13 of Dr. Bruce Betts' 2015 online Introductory Planetary Science and Astronomy course covers galaxies (our place in the Milky Way, types of galaxies, Hubble Deep Field), the Universe (determining distances, expansion of the universe, Big Bang theory and evolution of the universe, WMAP and Planck results, dark matter, dark energy, neutrinos), and life in the universe (Earth life requirements, astrobiology, SETI). Recorded at California State University Dominguez Hills.
In 1976, Carl Sagan appeared on The Tonight Show to talk about a crazy new idea: solar sailing. Nearly 40 years later, The Planetary Society is realizing this dream with a new spacecraft called LightSail designed to propel through space on beams of sunlight.
