The ESA's Rosetta space probe carries out detailed studies at closest vicinity of the nucleus of comet 67P/Churyumov-Gerasimenko (hereafter 67P) in order to reveal its physical properties, determine chemical composition, and there is a purpose the long-term tracking of the gas and dust release activity, as well as understanding the activity mechanisms of the comets. Comet 67P passed its perihelion just in August and apropos of this seminar talk summarizes the results claimed by the Rosetta mission so far and with special emphases of activity areas identified up to now. From the results claimed by studies of active surface holes and pits observed with the OSIRIS imaging system the near-surface interior structure of the nucleus may be revealed. These results were published by the OSIRIS team in a Nature journal paper with a coauthor who is a researcher of the MTA CSFK KTM CSI. In addition, the results claimed up to now by the instruments of Philae lander will also be presented in brief.
