Astronomers predict possible birthplace of Rosetta-probed comet 67P

Canadian researchers have charted a path that most likely pinpoints the very origins of 67P/Churyumov-Gerasimenko, the comet studied intensively by ESA’s Rosetta spacecraft. Western University astronomers believe that 67P is made from primordial material and relatively new to the inner parts of our solar system, having only arrived about 10,000 years ago.

How comets break up and make up

For some comets, breaking up is not that hard to do. A new study indicates that the bodies of some periodic comets — objects that orbit the Sun in less than 200 years — may regularly split in two, then reunite down the road. This may be a repeating process fundamental to comet evolution.

Philae’s descent to comet 67P

3 August 2015 Astronomy Now

Recently released images compiled into a movie show the descent of the European Space Agency’s Philae lander to its first touchdown site, Agilkia, on Comet 67P/Churyumov–Gerasimenko on 12 November 2014. The image sequence starts just over two miles from the comet, and the final image is from just 9 metres above the landing site.
