More Earth-like planets possible in Universe

A new research suggests that there may be more earth-like planets in the universe than we thought. A new study by UCLA (University of California, Los Angeles) scientists suggests that Earth-like planets are not uncommon in the universe. The study is the first to look in detail at the chemistry of rocky exoplanets to determine whether it is similar to or different from that of Earth. The researchers worked out a new method of analyzing the geochemistry of planets outside of our solar system. They focused on six most common rock elements: iron, oxygen, magnesium, aluminum, silicon and calcium. The rock formations suggested that more earth like planets in the universe exist and humans can live on them. Fun fact When venturing into space, astronauts wear spacesuits which have to be warmed, cooled, pressurised and supplied with fresh air. This takes six hours for them to put on!
