Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.
NASA dropped a bombshell this past week: The Kepler Space Telescope has discovered the most Earth-like planet to date. The rocky planet is slightly larger and warmer than our world, but it orbits a star and has the right conditions for liquid water. Meanwhile, the search for alien life goes on -- and Stephen Hawking gave his support to a $100 million project seeking to find out if we're alone in the universe. Exploring distant worlds is a challenging endeavor -- last week NASA proposed a novel robotic spacecraft that could harvest wind energy while surveying gas giants like Jupiter. And the Smithsonian Institution launched a Kickstarter to save Neil Armstrong's moon landing space suit, which is starting to fall apart after years of storage.
