The Latest Breaking News from Avi Loeb

Last summer, a Harvard professor claimed tiny pellets of iron came from beyond our solar system. But new analyses suggest that they likely originated much closer to home.

The discovery was quite interesting because, although such spherules are distributed globally, it is not easy to recover them from the depths of the ocean bed – requiring a dredging operation with a powerful magnet.

‘None of the evidence’ presented is ‘sufficiently convincing’ to infer they are from outside the Solar System
