Astronomers have been scrutinising high-definition photos of Comet 67P/Churyumov-Gerasimenko sent back by the Rosetta spacecraft.
And now a shortlist of five possible sites that could become the location for the first-ever landing on a comet, have been drawn up by the European Space Agency (Esa).
In mid-November, Esa intends to send down a robot laboratory named Philae, which will harpoon itself to the comet’s surface and carry out a battery of scientific tests, the results of which astronomers hope will help them work out how planets formed.
