The Jaw-Dropping New Plan To Send A Robot On A 1,000 Years Journey To An Alien Planet

Finding alien planets orbiting other stars is easy. Astronomers have found over 6,000 of them in just the last decade, but very few are considered even possibly habitable. Scientists have dozens of telescopes on the ground and in space that can find them and now even study their atmospheres for signs of life. Most are around small, dim red dwarf stars simply because current...
