A team of astronomers from the University of Wesrter (Australia), in collaboration with the International Centre for Radio Astronomy Research (ICRAR, for its acronym in English), has found two equal galaxies to the Milky Way in the nearby universe.
Until now it was thought that the Milky Way galaxy was unique because it compared only with the closest. However, a recent study found closer galaxies similar to ours. “What was needed was to have telescopes powerful enough to detect this type of galaxies and large sections of the sky observed “Aaron pointed Robotham, author of the study.
The study found 14 systems of galaxies similar to the Milky Way, “of which two have an almost exact match with her” indicated Robotham.
The researchers were able to detect that 3 percent of galaxies similar to the Milky Way have, like this, companion galaxies like the Magellanic Clouds , which surprised the researchers, because these “are very rare in the universe.”
Both the Great and the Small Magellanic Cloud, form a cosmic composition blocks to the Milky Way . In analyzing other constellations, a few have galaxies orbiting around like this dwarf galaxy.
“Never before had found a galaxy ‘twin’ to the Milky Way, but not surprisingconsidering how hard it is , “said the researcher, who has suggested that” so far the system had not reached “that could make this type of analysis of the Universe “.
Now, the research team is working on telescopes of New South Wales and Chile to study the two systems found equal to the Milky Way.
