Here's a neat video posted by SungrazerComets (the Twitter identity of the U.S. Naval Research Laboratory's Sungrazing Comets website) this morning.
Watch a conversation I had with planetary astronomer Britney Schmidt about Europa and the current state of outer planets exploration! Also, bonus video of an earlier hangout with Robbie Herrick.
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.
