NASA: DNA Found on Meteorites Indicates Life May Have Originated in Space

NASA researchers have found the building blocks for life in meteorites, indicating that the components for life on Earth may have originated in outer space.

"People have been discovering components of DNA in meteorites since the 1960s, but researchers were unsure whether they were really created in space or if instead they came from contamination by terrestrial life," said Dr. Michael Callahan, lead researcher of the discovery. "For the first time, we have three lines of evidence that together give us confidence these DNA building blocks actually were created in space."
