Scientists have recently found seven planets surrounding a sun all nearly 40 light years away. According to NASA, “‘This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,’ said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. ‘Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.’” It has also been shown that NASA scientists can measure the chemical concentration within the atmosphere of these planets to test what kinds of life inhabit the newfound planets. For example, plants produce oxygen and some microorganisms produce methane. These planets are all almost the exact same size as Earth and have similar terrain, further increasing the possibility for life. “Of all the planets we’ve found, this has risen to the top as the most exciting (for) the potential of studying habitability,” says Boston University’s Philip Muirhead, who was not involved with the study.
