Comet 67P/Churyumov-Gerasimenko, the target of ESA’s Rosetta mission, is getting dusty. New images show a hazy envelope, or dust coma, developing around the comet’s core. The comet makes one full rotation in 12.4 hours, 20 minutes shorter than astronomers previously thought.
The new data will be factored into Rosetta’s rendezvous with the comet, which is slated for August 2014.
