Very Large Telescope captured galaxy absorption of gas

Astrophysics from the Southern European observatory (ESO) photographed a galaxy’s

absorption of gas clouds surrounding it. The new data obtained with help of Very Large telescope (VLT) are remarkable that the galaxy is removed from Earth on distance more than ten billion light years. And respectively it is visible in that look in which was during an era of the young Universe. As at such distance the galaxy appears the smallest even at supervision through Very Large telescope (VLT), astronomers had to use indirect methods for an assessment of volume of absorption of gas and definition of details of process. Scientists used the behind a galaxy even more remote quasar settled down: the bright source of the radiation representing an active kernel of galaxies with a supermassive black hole. Illumination by a quasar allowed to carry out the spectral analysis of a galaxy and to reveal inaccessible to supervision in usual conditions gas clouds. On the basis of the obtained data scientists drew a conclusion that at the expense of absorption of gas occur not only increases in weight of a galaxy, but also formation of new stars. The considerable part of weight of gas which formed a galaxy is spent in the course of emergence of the first stars. Therefore absorption of gas clouds plays an important role in evolution of galaxies: at the expense of this process of a galaxy can support formation of stars more long.
