That would be 50% too soon. Stupid comet. Never learned standard theory.Currently, still more than 450 million kilometers are separating 67P from the Sun. Based on a rich history of ground-based observations scientists expect a comet’s activity to pick-up noticeably once it comes within 300 million kilometers of the Sun. “Being able to monitor these emissions from up close for the first time gives us much more detailed insights,” says Sierks. From the OSIRIS images, the team now wants to derive a better understanding of the evolution of cometary activity and the physical processes driving it.
