Free Online Course: The Science of the Solar System


CalTech is offering a free online course, The Science of the Solar System. Featuring CalTech’s Michael Brown, the course will explore the solar system using concepts from physics, chemistry, biology, and geology. Dr. Brown will share the latest from Mars, explore the outer solar system, ponder planets outside our solar system, and search for habitability in the universe. And the course is free! Sessions begin March 31.

LROC Northern Polar Mosaic


The Lunar Reconnaissance Orbiter Camera (LROC) team assembled 10,581 Narrow Camera Angle images, collected over four years, into a spectacular northern polar mosaic. The LROC Northern Polar Mosaic  (LNPM) is likely one of the world’s largest image mosaics in existence, or at least publicly available on the web, with over 680 gigapixels of valid image data covering a region slightly larger than the combined area of Alaska and Texas — at a resolution of 2 meters per pixel!

Web viewers can zoom in and out, and pan around an area. The mosaic provides enough detail to see textures and subtle shading of the lunar terrain. Consistent lighting throughout the images makes it easy to compare different regions.
