A sample of material collected from the surface of the near-Earth asteroid Bennu has been found to contain abundant water and carbon, the US space agency NASA said, offering more evidence for a theory that life on Earth was seeded from outer space.
The findings were announced on Wednesday as NASA gave the public a first glimpse of what scientists found inside a sealed capsule that was returned to Earth last month after carrying material scooped from the 4.5-billion-year-old asteroid’s surface by the OSIRIS-REx spacecraft.
