Scientists have found amino acids, the building blocks of life, in meteorites from Sudan. This is not the first time that's happened, but it is the first time they turned up in meteorites that had been naturally subjected to temperatures of 1,100 degrees Celsius. There shouldn't have been any organic compounds left, and experts like NASA astrobiologist Daniel Glavin are not certain why. But this does make it more plausible that life COULD have come to Earth from elsewhere.
