There’s certainly nothing living on the asteroid Bennu, an airless, 1,614-ft. rubble pile orbiting the sun about 40.2 million miles from Earth. But that doesn’t mean that Bennu hasn’t all at once become one of the most biologically interesting objects in the solar system.

Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission from a near-Earth asteroid named Bennu.

Bennu contains minerals and thousands of organic molecules, including the chemical components that make up DNA.

Material retrieved from the asteroid Bennu by NASA’s OSIRIS-REx spacecraft shows that all the basic building blocks of life were astonishingly widespread in the early solar system

It took a while for scientists to gain access to the samples that NASA’s OSIRIS-REx mission took from the asteroid Bennu, but the wait is proving to be worth it. A new study published January 29 in Nature describes an unexpected discovery in the material delivered by OSIRIS-REx: residues of compounds left over by the evaporation of liquid water.

A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.

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.

Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best evidence to date that such space rocks may have seeded early Earth with the raw ingredients that fostered the emergence of living organisms.

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.
