+ MYSTERIOUS RIPPLES FOUND RACING THROUGH PLANET-FORMING DISC [HEIC1521]
Using images from the NASA/ESA Hubble Space Telescope and ESO's Very Large Telescope, astronomers have discovered never-before-seen structures within a dusty disc surrounding a nearby star. The fast-moving wave-like features in the disc of the star AU Microscopii are unlike anything ever observed, or even predicted, before now.

+ COMETWATCH 1 OCTOBER
Today's CometWatch entry is an image from Rosetta's NAVCAM taken on 1 October 2015, at a distance of 1323 km from the nucleus of Comet 67P/Churyumov-Gerasimenko.

+ COMETWATCH 30 SEPTEMBER - FAR, FAR AWAY
Today's CometWatch entry is an image taken by Rosetta's NAVCAM on 30 September 2015, about 1488 km from the nucleus of Comet 67P/Churyumov-Gerasimenko. The image was taken a few hours after the spacecraft had reached the farthest point - 1500 km from the nucleus - on its far excursion to study the coma and plasma environment of 67P/C-G on a broader scale.

+ ROSETTA'S FIRST PEEK AT THE COMET'S SOUTH POLE
Using the Microwave Instrument for the Rosetta Orbiter (MIRO), scientists have studied the comet's southern polar regions at the end of their long winter season. The data suggest that these dark, cold regions host ice within the first few tens of centimetres below the surface in much larger amounts than elsewhere on the comet.

+ AN UPDATE ON COMET 67P/C-G'S WATER-ICE CYCLE
Earlier we reported on the daily water-ice cycle of Comet 67P/Churyumov-Gerasimenko that was observed in a specific region of the comet's neck by Rosetta's VIRTIS instrument, in September 2014. Yesterday at the European Planetary Science Congress, animations were shown covering the period 1 August 2014 to 10 February 2015.
