A handout image of the comet 67P/Churyumov-Gerasimenko made available by the ESA

A handout image captured October 23, 2014, from a distance of about 7.8 km (4.8 miles) from the surface, of the comet 67P/Churyumov-Gerasimenko, made available by the European Space Agency (ESA) on November 11, 2014. European scientists launched a probe from spaceship Rosetta on November 12, 2014, in an historic attempt to examine the surface of a comet, starting a seven-hour descent that is seen as the most difficult phase of a ten-year mission.
