NASA Says Asteroid Soil Contains 'Building Blocks for Life'

NASA researchers have been studying rock and dust brought back to Earth from the asteroid, Bennu. Those particles revealed what scientists call "the building blocks for life." Researchers found 14 of the 20 amino acids that life on Earth uses to make proteins. NASA makes it clear that its findings do not show evidence of extraterrestrial life itself, but that under the right circumstances, life could be possible.
