The water was discovered in comet 67P It recently reached the European Rosetta and sat it on the lander Philae. Now, the data showed that the H2O molecules are in the gases emanating from the comet. Some scientists believed that it was on comets may have come to Earth a lot of water. However, recent analysis has shown that the water on the 67P is a little different from this earthly. On the comet is in fact much higher concentration of particles of so-called heavy water.
– So now these possible sources of water on Earth, we must look at other types of comets or asteroids – a member of the British BBC says Professor Monica Grady project.
Other scientists, however, suggest that you have to wait for a more detailed analysis. Publishes research results weekly “Science”.
