2017 was a year of groundbreaking discoveries and record-setting exploration at NASA. The moon became a focal point for the agency. NASA gave us unique coverage of the first coast-to-coast total solar eclipse in the U.S. in 99 years, announced the most Earth-size planets ever found in the habitable zone of a star outside our solar system, and more. Here are photos of the year’s highlights in the solar system and beyond. (NASA)
