Today's CometWatch is an image taken with Rosetta's NAVCAM on 5 February 2016, when the spacecraft was 53.4 km from the nucleus of Comet 67P/Churyumov-Gerasimenko. At these closer distances the comet is now close to filling the camera’s field of view.
There are no large caverns inside Comet 67P/Churyumov-Gerasimenko. ESA’s Rosetta mission has made measurements that clearly demonstrate this, solving a long-standing mystery.
Today's CometWatch is an image taken with Rosetta's NAVCAM on 28 January 2016, when the spacecraft was 67.6 km from the comet nucleus.
In this new NAVCAM view, taken 21 January, Comet 67P/Churyumov-Gerasimenko’s small lobe and its distinctive Hatmehit depression face directly towards Rosetta.
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.
