Median stack images of P/2016 G1 obtained with the OSIRIS instrument of the 10.4m GTC through a Sloan r′ filter, at the indicated dates. North is up, East to the left. The directions opposite to Sun and the negative of the orbital velocity motion are shown. The arrow in the middle of central panel indicates the westward feature that emerges from the inverted C-shaped mentioned in the text. The dimensions of the panels (from left to right, in km projected on the sky at the asteroid distance) are 27930×27930, 26305×26305, and 27025×27025. The images are stretched linearly in brightness, with maximum intensity levels, from left to right, of 8×10−14, 5×10−14, and 4×10−14 solar disk intensity units...

Image montage showing the Maunakea Observatories, Kepler Space Telescope, and night sky with K2 Fields and discovered planetary systems (dots) overlaid. An international team of scientists discovered more than 100 planets based on images from Kepler operating in the ‘K2 Mission’. The team confirmed and characterized the planets using a suite of telescopes worldwide, including four on Maunakea (the twin telescopes of Keck Observatory, the Gemini­North Telescope, and the Infrared Telescope Facility). The planet image on the right is an artist’s impression of a representative planet.
