Samples from asteroid Bennu reveal it contains ancient stardust older than the solar system, organic materials, and ices from interstellar space, providing insights into the early cosmos and the asteroid's violent history of formation and reassembly after a collision.
Scientists have criticized the recent claim by Harvard astrophysicist Avi Loeb that spherical materials found under the ocean are of interstellar origin, stating that the evidence is not yet convincing and inconsistent. While the presence of unusual metal particles suggests the materials may have come from outside Earth, the conclusions drawn from the analysis are deemed inconsistent. The research is pending peer review, and until then, scientists are cautious about accepting the claim that the materials are from an alien spacecraft or of extraterrestrial technological origin.
