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.

The Rosetta space probe woke up and is now ready to reach the comet 67P/Churyumov-Gerasimenko

Yesterday it was almost evening in Europe when ESA received the first signal from the spacecraft Rosetta. It confirmed that it regularly awakened after spending about two and a half years in hibernation. The testing phase started to ensure that all of its instruments are functioning properly. Rosetta is now en route to the comet 67P/Churyumov-Gerasimenko.

The comet ISON has been destroyed… or not

In recent months, the comet ISON was the center of attention not only of astronomers, amateur and professional, but also of the general public because it had been mentioned as a possible comet of the century for its great brightness. It was followed and photographed by instruments on the ground and in space, including the good old Hubble Space Telescope, especially yesterday, when it moved close to the Sun. It was the most critical moment and it seemed that ISON was destroyed by the Sun’s gravity but after a few hours at least some fragments came out.
