Rosetta Space Probe Sees Its Own Spooky Shadow On Comet 67P
Punxsutawney Phil wasn’t the only one who saw his shadow last month.
Just 12 days after the groundhog ogled his umbra on Feb. 2, the European Space Agency’s comet-hunting space probe, Rosetta, captured a photo of its shadow on Comet 67P.

The photo, taken by the probe’s OSIRIS camera, is being called the highest-resolution image yet taken of Comet 67P. OSIRIS actually consists of two independent camera systems operating in the visible, near-infrared and near-ultraviolet ranges. ESA released the image on March 3.
“Images taken from this viewpoint are of high scientific value,” Holger Sierks, OSIRIS principal investigator from the Max Planck Institute for Solar System Research in Göttingen, Germany, said in a written statement. “This kind of view is key for the study of [dust] grain sizes.”
