Astronomers, data-processing space mission “Rosetta”, reported that water molecules on the surface of comet Churyumov — Gerasimenko turned out to be older than the Solar system.

Automatic interplanetary station “Rosetta” was launched in 2004 to comet 67P/Churyumov — Gerasimenko. The station consisted of two parts — the actual probe “Rosetta” and the lander “Fily”.
12 November 2014, Philae descended to the comet’s surface and within six months, during short sessions transmit data: imagery of the surface isotopic composition.
30 September 2016 the program was completed, the probe “Rosetta” made a controlled collision with a comet Churyumov — Gerasimenko. Interplanetary monitoring system was developed and supervised by the European space Agency together with NASA. Russian scientists indirectly participated in the mission by developing some analytical equipment for vehicles.

Under “Rosetta” sensor for ion and neutral analysis ROSINA could determine the isotopes of different atoms, as well as rare organic molecules released from the comet’s nucleus in the form of gases. Measurements carried out by the analyzer ROSINA, help to know where the atom has arisen (e.g. in a supernova) or, in the case of organic molecules, under what conditions (temperature, pressure) it was synthesized.
