Pristine samples of the asteroid Bennu transported to Earth contain the "basic building blocks" for life, shedding new light on how life began on our planet.

Samples from asteroid Bennu have delivered insights into the origins of Earth’s water and the organic molecules that may have seeded life.

When asteroids like Bennu hit the young Earth, they could have provided a complete package of complex molecules and the ingredients essential to life, such as water, phosphate and ammonia. Together, these components could have seeded Earth’s initially barren landscape to produce a habitable world.
