Philae manager Stephan Ulamec provides an update on the status of the lander following it’s arrival on the surface.
The sharpest, most detailed observations of a comet breaking apart have been captured with the NASA/ESA Hubble Space Telescope. The images suggest that the roughly 4.5-billion-year-old comet, named 332P/Ikeya-Murakami, may be spinning so fast that material is ejected from its surface. The resulting debris is now scattered along a 3,000-mile-long trail.
Amateur and professional astronomers are invited to provide observations of comets 41P/Tuttle-Giacobini-Kresák, 45P/Honda-Mrkos-Pajdušáková, and 46P/Wirtanen that will pass by Earth at distances ranging from 0.08 to 0.15 astronomical units. Such close approaches of a trio of comets within the next two years are rare and typically occur only once every few decades.
