The first map of the comet 67P/Churyumov-Gerasimenko has been unveiled

A group of scientists who are studying the comet 67P/Churyumov-Gerasimenko has created a map based on the analysis of surface images taken by the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) instrument of the Rosetta space probe. The result is that the comet can be divided into different regions that have distinct physical appearancec. This map shows that it’s much more than a large rock mixed with ice.

The Rosetta space probe is about to start its descent towards the comet 67P/Churyumov-Gerasimenko

The Rosetta space probe reached the comet 67P/Churyumov-Gerasimenko almost a month ago but remained at a distance from it of not less than 52 kilometers (about 32 miles). ESA’s scientists spent the last few weeks studying the comet, also to determine the route to follow for the probe and the Philae lander. Today, Rosetta is scheduled to start the series of maneuvers that in a few days will bring it at a distance of approximately 29 km (about 18 miles) from the comet to arrive later about 10 km (a bit more than 6 miles) from it.

The Rosetta space probe has reached the comet 67P/Churyumov-Gerasimenko

The Rosetta space probe has just completed the last series of maneuvers that brought it into the orbit of the comet 67P/Churyumov-Gerasimenko. This stage of the Rosetta mission started some time ago and in recent weeks it sent images and other data that were very interesting but now, after more than 10 years of traveling, the main phase of its mission is starting.

The Rosetta space probe revealed new surprising information about the comet 67P/Churyumov-Gerasimenko

ESA’s Rosetta space probe is continuing its approach to the comet 67P/Churyumov-Gerasimenko and the photos that are coming are more and more decomaed. In July, the images of the comet’s nucleus had revealed its binary nature, now scientists but also merely curious people can see it in a much better quality. Its coma begins to show an interesting activity too and Rosetta has provided more surprising data.

The Rosetta space probe has revealed the double nucleus of the comet 67P/Churyumov-Gerasimenko

ESA’s Rosetta space probe awakened in January 2014 after a journey that lasted almost ten years. In recent weeks, it started sending pictures of its target, the comet 67P/Churyumov-Gerasimenko. Yesterday, CNES, the French space agency, published a composition of photos taken on July 11 which show that the comet is composed of two nuclei that are attached, a fact that makes the Rosetta mission even more extraordinary.

A comet with a retrograde orbit found by the NEOWISE Space Telescope

The NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) Space Telescope discovered his first comet after starting its new mission last year. On February 14, 2014, during one of its scans of space in search of objects that can cross the Earth’s orbit, it found a comet, which has been designated C/2014 C3 (NEOWISE). Astronomers quickly realized that it’s a weird comet because its orbit is retrograde.
