OSIRIS-REx Found All DNA Letters on Asteroid in Panspermia Breakthrough

What was said

"All of the nucleobases of our DNA, not just little molecules, the letters of our DNA and our RNA are in that sample. We don't think that's a coincidence."

NASA's OSIRIS-REx asteroid sample return mission discovered all nucleobases used in human DNA and RNA on asteroid Bennu, along with bases not used by Earth life. Thaller called this a profound discovery supporting panspermia theory—that the building blocks of life literally rain down from space on asteroids.
