Scientists claim that approximately 65 million years ago the Earth was hit by a huge rock coming from space. The crater caused by the blast is supposed be over 100 miles in width and according to experts the energy it released was 100 trillion tons of TNT. This power is over 1 billion times the power of the Nagasaki and Hiroshima atom bombs. The result of the blast was the extinction of about 75% of the species inhabiting the Earth, including the dinosaurs.
According to new hypotheses the huge blast may have sent large rocks from the Earth to Mars and Europa – the satellite of Jupiter. Scientists believe that rocks bigger than 3 meters have travelled all the way to Mars and Jupiter’s satellite Europe packed with various living species.
Thus, researchers suggest that any forms of life are found on other planets and their satellites we shouldn’t assume their origin is independent because they may have come from the Earth. The research and debate of such hypothesis continues.
