We are all in the gutter, but some of us are looking at the stars.

STEREO Watches the Sun Blast Comet PanSTARRS
This movie from the Solar Terrestrial Relations Observatory (STEREO) shows comet PanSTARRS as it moved around the sun from March 10-15,2013 (repeated three times). The images were captured by the Heliospheric Imager (HI), an instrument that looks to the side of the sun to watch coronal mass ejections (CMEs) as they travel toward Earth, which is the unmoving bright orb on the right. The bright light on the left comes from the sun and the bursts from the left represent the solar material erupting off the sun in a CME. While it appears from STEREOís point of view that the CME passes right by the comet, the two are not lying in the same plane, which scientists know since the cometís tail didnít move or change in response to the CMEís passage.

"Space is big. Really big. You just won't believe how vastly, hugely, mind-boggingly big it is. I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space." - The Hitch-Hikers Guide to the Galaxy - Douglas Adams 1952 - 2001
