Lecture 4 of Dr. Bruce Betts' online Introductory Planetary Science and Astronomy course covers the Moon, Mercury (characteristics, geology, core, exploration, water ice at poles), the Terrestrial Planet Atmospheres/Triad Planets -- a comparison of Venus, Earth, and Mars and why their atmospheres are so different, including discussions of the habitable zone, greenhouse effect, temperature systems (Kelvins, Celsius, Fahrenheit), and the carbon cycle. Recorded at California State University Dominguez Hills.
Lecture 3 of Dr. Bruce Betts' online Introductory Planetary Science and Astronomy course covers optical, radio, and space telescopes, eclipses, and an introduction to the Moon including lunar tides, phases and impact cratering. Recorded at California State University Dominguez Hills.
Lecture 2 of Dr. Bruce Betts' online Introductory Planetary Science and Astronomy course covers easy things to see in the night sky without a telescope, and the electromagnetic spectrum (from gamma rays to visible to radio waves) -- what it is, and how and why we use different wavelength regions to explore planets and even learn their compositions. The class begins with guest Mat Kaplan, Media Producer for The Planetary Society and Bruce and Mat record a What's Up segment for Planetary Radio. Recorded at California State University Dominguez Hills.
The secrets of the universe are out there, waiting to be discovered. But to find them, we have to go into space. We have to explore.
Take a tour of the Solar System in class 1 of Dr. Bruce Betts' online Introductory Planetary Science and Astronomy course at California State University Dominguez Hills.
Space exploration had a very exciting year, from Scott Kelly's record-breaking Year in Space aboard the ISS to a launch to an asteroid and much more in between. Robert Picardo takes a look back at some of the space science highlights of 2016.
A reading of Carl Sagan's Pale Blue Dot by Star Trek's Robert Picardo, who also serves as a member of The Planetary Society Board of Directors and is the host of our monthly email newsletter, The Planetary Post.
Carl Sagan famously said of science: “When you're in love, you want to tell the world.” That's how we feel about space exploration. Watch as Bill Nye, Nichelle Nichols, Leland Melvin, Emily Lakdawalla, Robert Picardo, Casey Dreier, Mat Kaplan, Bruce Betts, and CaLisa Lee tell their stories of how they fell in love with space.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
