Amateur and professional astronomers alike have been monitoring changes in Comet 67P/Churyumov-Gerasimenko’s tail, which, since December, has been exhibiting two prominent structures.
Today's CometWatch features a NAVCAM image taken on 17 January 2016, when Rosetta was 83.4 km from the comet nucleus. The scale is 7.1 m/pixel and the image measures 7.3 km across.
Since the start of the 2016 we have been treated to a variety of views of Comet 67P/Churyumov-Gerasimenko from Rosetta’s OSIRIS wide- and narrow-angle cameras through their “Image of the Day” website.
Today's CometWatch entry is a double feature, showing two NAVCAM images taken about twelve hours apart, on 18 and 19 December 2015, when Rosetta was around one hundred km from the comet nucleus.
Today's CometWatch entry is a NAVCAM image taken on 7 December 2015, when Rosetta was 103.1 km from the comet nucleus.
Rosetta’s OSIRIS camera team has launched a new website to showcase their recent images of Comet 67P/Churyumov–Gerasimenko.
Astronomers have responded to the buzz about a mysterious dimming star by studying data from NASA's Spitzer Space Telescope. They conclude the dimming was probably caused by a family of comets passing in front of the star.
This week’s Cometwatch entry was taken by Rosetta’s NAVCAM on 27 November 2015 when the spacecraft was 124 km from the nucleus of Comet 67P/Churyumov-Gerasimenko.
Today's CometWatch entry is a NAVCAM image taken on 17 November 2015, when Rosetta was 141.4 km from the nucleus of Comet 67P/Churyumov-Gerasimenko. The spacecraft has not been this close to the nucleus since weeks before perihelion, when the increased amounts of dust due to enhanced comet activity started interfering with navigation and Rosetta remained at larger distances from 67P/C-G.
As announced in June along with confirmation of the mission’s extension, Rosetta teams are planning to end the operational phase of the mission in a controlled impact of the orbiter on the surface of Comet 67P/Churyumov-Gerasimenko at the end of September 2016. While the specific details of the trajectories and impact site are still under discussion, ESA’s Rosetta Spacecraft Operations Manager Sylvain Lodiot, Project Scientist Matt Taylor, and mission manager Patrick Martin, share some background information on the planning of this dramatic mission finale.
