The first stars and galaxies of the Universe

Composition of the first stars and galaxies of the Universe

Scientists learned of what were constructed the first stars and galaxies of the Universe. Thanks to a radio telescope of CSIRO which is located in the Australian Observatory Parkes, astronomers could find the main construction material from which the first stars and galaxies of our Universe were created. BY the words of Professor Ron Ekers the telescope of CSIRO is one of the few telescopes in the world which could carry out such difficult work and find a material from which the first stars and the first galaxies in the Universe were created. It appeared that cold molecular hydrogen (H2) was the key material of forming the first stars and galaxies. It was found in early stars and galaxies with help of CO intermediary gas which radiates radio waves. To make the discovery, scientists studied the remote protogalaxies and other protoobjects of the Universe. These protoobjects are located more, than in 10 000 million light years from our Solar System. And scientists even could measure quantity of CO and H2 in two remote galaxies. The studied galaxies of MRC 1138-262 and SPT-S 053816-5030.8 showed very large amount of cold H2 hydrogen. Recently scientists conducted some curious researches with use of a telescope of CSIRO connected with studying of molecular hydrogen in far galaxies. During the first of them astronomers found structure from molecular H2 which they called Spiderweb. This structure was widely stretched on the Universe, approximately at distance in 10 billion light years from us. During other research scientists could determine the speed of formation of stars in galaxies with high precision. They determine the speed by amount of the CO gas found in galaxies, lying even further from Earth, than the Spiderweb.
