As the comet approaches the Sun Churyumov-Gerasimenko is heated more. Emission is water vapor, gas, dust - all thrown in okruyuschayuschee space from the comet's nucleus. March 12 space probe Rosetta сфотографировала comet at a distance of 75 kilometers, and this photo has been very successful: in the photo, scientists have discovered one of the emissions of substances that are already en masse.
The picture was not the only one - OSIRIS camera pictures made with a frequency of two minutes. At the same time on one of the pictures have nothing, and the second is seen the finished dust-gas stream. Emission length was 900 m, the velocity of propagation in material 8 m / s. The most interesting thing is that the release appeared on the side that is not illuminated by the sun.
The usual model of convergence of the comet with the sun warming involves areas of the comet, which highlights the sunlight, and here, according to scientists, and should go the main activity on the release of the substance of the comet. Now experts are studying this particular case, as well as many other interesting phenomena occurring with the comet now.
It should be noted that the minimum distance to the Sun. Comet Churyumov-Gerasimenko suit on August 13. According to scientists, the activity of all the processes taking place now on the comet, up to this point will only grow. Maybe in a few days, thanks to the increased light and heat of the comet's surface, wake probe Philae.
