(Phys.org) —Since early August 2014, Rosetta has been enjoying a close-up view of comet 67P/Churyumov–Gerasimenko. Meanwhile, astronomers on Earth have been busy following the comet with ground-based telescopes. As Rosetta is deep inside the 'atmosphere' coma – it was 100 km from the nucleus on 6 August, and has been getting much closer since then – the only way to view the whole comet is to 'stand back' and observe it from Earth.
