On the evening of November 9, which would have been Carl Sagan's 78th birthday, the Planetary Society brought together some of his best friends to share their memories. We were also joined by four young scientists whose career choices were influenced by Carl.
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.
Whether you heard the show or not, you'll be fascinated by Emily's great presentation. It also proves she is not part of the great conspiracy that is hiding evidence of alien bases on the moons of Saturn!
I probably crammed too much into today's class: an hour-and-a-half whirlwind tour through the cameras on the rovers and Cassini, how to access their raw images on the Internet, and some basic processing that you can do with each of them.
I finally prevailed in hosting the first in my series of classes on processing space images for amateurs this morning, while most people who were not working were probably watching the flawless launch of Space Shuttle Atlantis.
