A team of Dutch and Scottish researchers led by Simon Portegies Zwart (Leiden University) has found an explanation for the chaotic behavior of the orbit of Halley's Comet. The findings are accepted for publication in the Monthly Notices of the Royal Astronomical Society.
This week’s CometWatch entry soaks up the sights of a number of regions on both the small (right) and large (left) lobes of Comet 67P/Churyumov-Gerasimenko. The image was taken by Rosetta’s NAVCAM on 17 June from a distance of 30.8 km, and the image measures about 2.7 km across.
CBET nr. 4282, issued on 2016, June 05, announces the discovery of an apparently asteroidal object (magnitude ~18.5) found on CCD images taken on May 31 with the 3.5-m f/1 Space Surveillance Telescope on Atom Peak in the White Sands Missile Range, NM, USA, in the course of the LINEAR survey.
This image of Comet 67P/Churyumov-Gerasimenko was taken by Rosetta’s NAVCAM on 13 June 2016 from a distance of 28.5 km to the centre of the comet.
This week's CometWatch entry is an image of Comet 67P/Churyumov-Gerasimenko taken with Rosetta's NAVCAM on 2 June 2016, when the spacecraft was 23.6 km from the comet centre.
This week's CometWatch entry is an image of Comet 67P/Churyumov-Gerasimenko taken with Rosetta's NAVCAM on 19 May 2016, when the spacecraft was 7.6 km from the centre of the comet nucleus and about 5.6 km from the surface.
This week’s CometWatch entry from Rosetta’s NAVCAM was taken on 15 May 2016 when the spacecraft was 9.88 km from Comet 67P/Churyumov-Gerasimenko.
This sequence of images taken by NASA's Hubble Space Telescope shows Comet 252P/LINEAR as it passed by Earth. The visit was one of the closest encounters between a comet and our planet.
This week's CometWatch is an image taken with Rosetta's NAVCAM on 1 May 2016, when the spacecraft was 18.8 km from the nucleus of Comet 67P/Churyumov-Gerasimenko.
