Rosetta, a European space agency space probe, reached comet P67, and captured this image taken in August 2014. In November 2014, a space probe lander named Philae separated from the Rosetta and landed on the comet's surface. This was the first time a robotic space probe successfully landed on a comet.However, the lander was not able to collect light needed for recharging its battery and contact with it was lost after two days.
Comets are large objects composed of ice, frozen carbon dioxide and rock. Comets have an elliptical orbit around the sun and reappear every few years. The picture shows comet C/2006 P1 evaporate as it nears the sun, leaving behind a tail of fumes and dust millions of kilometers long, which is illuminated by the sun. A plane with a flashing light crossed the comet’s tail as the picture was being taken, but the comet’s progress across the sky is slow, like that of the moon, and we do not notice it.
