Some impressive numbers from Rosetta’s mission. Click for full res!   Summary Rosetta’s mission lasted 12 years 6 months and 28 days, from launch on 2 March 2004 to mission end on 30 September 2016. During that time,...

Rosetta’s comet contains ingredients for life

This story is mirrored from the ESA Web Portal Ingredients regarded as crucial for the origin of life on Earth have been discovered at the comet that ESA’s Rosetta spacecraft has been probing for almost two years....

CometWatch 19 May

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...

Twin tails

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. “Current indications from the data we’re collecting of Comet 67P/C-G is that both features are...

OSIRIS images in Archive Image Browser

The Rosetta Downlink and Archive group is pleased to announce the release of Rosetta OSIRIS images from both the wide- and narrow-angle cameras (WAC and NAC, respectively) to the Archive Image Browser and to the Planetary Science Archive....

Amateur astronomers keeping an eye on the comet

This post is an interview with Padma A. Yanamandra-Fisher, a Senior Research Scientist at the Space Science Institute, USA, and the Rosetta Coordinator of Amateur Observations for 67P/C-G. Q: When did the amateur campaign to observe Rosetta’s...

First release of Rosetta comet phase data from four orb...

ESA’s Rosetta downlink and archive teams are very happy to announce the release today of the first wave of Rosetta instrument data from the “comet pre-landing phase” via the Planetary Science Archive. Data from four instruments are...

Chasing a comet from Earth – update on the professional...

An interview with Colin Snodgrass of the Open University, UK, who coordinates a consortium of professional astronomers observing Comet 67P/Churyumov-Gerasimenko from Earth in support of the Rosetta mission. Q: Rosetta has been ‘living’ with Comet 67P/Churyumov-Gerasimenko for...

Rosetta and Philae status update

Over the last few weeks, Rosetta has been flying along the terminator plane of Comet 67P/Churyumov-Gerasimenko, at distances from 180 km down to 153 km and at latitudes between 0 and 54 degrees, in order to find...

Getting to know Rosetta’s comet: boundary conditions

In January the first maps of Comet 67P/Churyumov-Gerasimenko were published, identifying 19 geomorphologically distinct regions on its surface. Six months on and much more work has been done on refining the boundaries between these regions. This blog...

CometWatch from Earth – 22 May

Astronomers using ESO’s ground-based Very Large Telescope (VLT) in Chile are watching the development of Comet 67P/Churyumov-Gerasimenko’s coma and tail from Earth. This image is based on data acquired on 22 May and is about 300 000 km...

Observing comet 67P/C-G with the Very Large Telescope

Guest post by Colin Snodgrass from the Max Planck Institute for Solar System Research, Germany. Colin coordinates a consortium of professional astronomers observing comet 67P/Churyumov-Gerasimenko from Earth. Since rendezvousing with Comet 67P/C-G in early August, Rosetta has...
