Learn easy things to look for in the night sky, and about the electromagnetic spectrum from gamma rays to radio waves in the video of class 2 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
Comet ISON captivated our world, and many of our world’s robotic emissaries for many months. But, alas, poor ISON is dead -- again. Here I wrap up our enthusiastic coverage of this multi-morphing zombie comet that tried to survive and re-survive as it came within one solar diameter of the Sun.
Comet ISON reached perihelion at 18:25 UT (10:25 PT) on November 28. It's an event that's was watched around the world, accompanied by tons of commentary and streams of photos. We will update this blog entry periodically with links to all the resources that we hear of for following the comet's progress.
We present an update and a video about the successful design, construction, and testing in a vacuum chamber by Honeybee Robotics of a prototype PlanetVac system, a new planetary surface sampling technique, sponsored by The Planetary Society. PlanetVac is a reliable system that effectively vacuums up planetary surface materials.
