Planetary exploration is in trouble. Massive budget cuts threaten to starve NASA’s planetary program for years to come. If you are as angered and frightened by this situation as I am, I ask you to make your voice heard. Please share this video. And tell Washington, “We Must Explore.”
If you want to test your planetary knowledge, or just have a masochistic love of tests, I’ve posted the midterm I’ve given to my students in my online Introductory Astronomy and Planetary Science class at California State University Dominguez Hills.
Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.
A new installment of our "Snapshots" video series examines the threat posed by asteroids on collision courses with our home planet. Emily Lakdawalla explains why it's so important to find, understand and learn to deflect these potential civilization enders.
The second episode of Emily Lakdawalla's new video series reveals the gigantic library of solar system images captured by NASA spacecraft, and explains why we've seen so few of them. Emily says they're all online, waiting for space geeks to turn them into gold.
I gave the first lecture of my Introduction to Astronomy and Planetary Science course last Wednesday, starting with a tour of the solar system. The course is Physics 195 at California State University Dominguez Hills.
