Samples taken from the asteroid Bennu are continuing to shed light on the origins of the solar system.
Scientists have been studying the samples since NASA's Osiris-REx spacecraft carried them back to Earth in 2020 and recently discovered that that they contain sugars and "a gum-like substance not seen before in astromaterials," NASA said.
The revelations — and how they can help answer big questions about the beginnings of life — are described in three new papers published Tuesday by the journals Nature Geosciences and Nature Astronomy.
