Utilizing the information from the telescope, researchers determined that there might be billions of Earth-like planets in the Milky Way cosmic system. Mars, on the other hand, has no Oxygen and effectively a very thin atmosphere that makes living beings vulnerable to the deadly UV rays of the sun.
