Asteroid Bennu Contains Something Older Than the Solar System, NASA Says

Jan 18, 2026
The OSIRIS-REx samples have transformed planetary science. For centuries, astronomy was a remote discipline. We could only look. We could study the light from stars and the reflection from asteroids, but we could never touch them. Now, we have entered the era of direct contact.

We can put the early universe under a microscope. We can slice it with ion beams. We can measure its isotopes. We went to Bennu to answer questions about the origin of the solar system. We returned with answers about the origin of ourselves.
