a Team of astronomers led Mahanoy Bhatavdekar from the European space Agency (ESA) used the observational data of the Hubble telescope to search for stars in the early Universe. The results of the study showed that galaxies formed much earlier than was believed until now.
a Brief report on the opening published on the ESA website. In addition to the data the Hubble space telescope, which had a major importance, we used the data of the Spitzer space telescope and ground-based Very Large Telescope of the European southern Observatory.
the Task of the scientists was the discovery of the so-called stars of population III. So theorists called stars that formed early in the Universe. It is believed to be the first generation of stars, created from the primary material resulting from the Big Bang.
Hence, these stars were supposed to be “made” entirely of hydrogen, helium and lithium are the only elements that existed before the processes in the cores of these stars can create heavier elements such as oxygen, nitrogen, carbon and iron.
Starting from this principle, scientists have developed a new technique. It allows you to remove the glare of bright galaxies in the foreground gravitational lenses. To use this technique was perfect the instruments of the Hubble telescope.
Thanks to him, scientists literally was able to look into the time interval from 500 to one billion years since the Big Bang. That’s where the researchers expected to find the stars of population III, but no evidence of their existence is not found.
However, this does not mean that they do not exist. The results of the study suggest that galaxies were formed much earlier than so far assumed by the astronomers. Furthermore, it is likely the emergence of the first stars in the Universe also has occurred much earlier than the theory assumes.
And it happened in the time interval, and look in which modern technologies not yet able. So the Hubble telescope it was not under force. However, in ESA the results of a study called the amazing discovery of the Hubble telescope, made in the early Universe.
