Astronomers from the Max Planck Institute for Radio Astronomy in Germany (Max Planck Institute for Radio Astronomy) found traces of water in the galaxy from Earth several billion light years away. The results of research astronomers published in the scientific journal Nature.
Helped to discover the so-called water maser emission. This particular type of electromagnetic radiation is emitted as a result of the energy content of clouds of interstellar matter (in this case water vapor) cosmic rays.
Under the influence of these rays pass water molecules in the first excited state, and then consistently "calm down" by emitting photons of the same frequency. The resulting radiation has a very narrow range and high intensity, so is a convenient object for study.
With the 100-meter Effelsberg radio telescope, astronomers have detected water maser emission in the light of the quasar MG J0414 +0534, remote from us at 11.1 billion light years. So far the object was "visible" to astronomers because of an effect known as "gravitational lens".
Among the more nearby galaxies maser sources are quite rare - like radiators contains only five percent of them. The new discovery shows the high prevalence of masers in the past.
In addition, as the quasars are active galactic nuclei, the scientists suggest that the pump source for the maser emission are supermassive black holes. This fact, according to astronomers, opens up new possibilities for the study of these enigmatic objects. Just tell us interesting news in detail.
