A video from NASA’s ScienceCast explaining what the Dawn mission probe has discovered while orbiting the distant asteroid — it may be the smallest terrestrial “planet” discovered, given that it might well have had flowing lava and volcanoes. For a mundane hunk of rock very far away, it sure had a surprisingly interesting past.
I love this stuff.
