The Most Earth Size, Habitable Zone Planets around a Single Star on This Week @NASA 02/24/2017

NASA held a news conference Feb. 22 at the agencys headquarters to discuss the finding by the agencys Spitzer Space Telescope of seven Earth-sized planets around a tiny, relatively nearby, ultra-cool dwarf star. Three of the planets in this system, known as TRAPPIST-1, are in the habitable zone the region around the star in which liquid water is most likely to thrive on a rocky planet. This is the first time so many planets have been found in a single star's habitable zone outside our solar system, and is the best target yet for studying the atmospheres of potentially habitable, Earth-sized worlds.
