Mysterious 'Oumuamua space object may help explain how life arose on Earth -NBCNewsMACH
Previous research on comets and other small bodies within our own solar system suggests that 'Oumuamua-like objects provide good thermal insulation and radiation shielding, she added. That's good news for any microbes that may be hitching a ride.
Astronomers have not yet identified 'Oumuamua's natal star system, so we don't know long ago the object was ejected into the dark and frigid wastes. But it may have been traveling through interstellar space for 10 million years or more, Meech said. Previous work by Harvard University astronomer Avi Loeb and others, along with Sigurdsson's own calculations, suggests that about 100 'Oumuamua-like objects have slammed into Earth over our planet's nearly 4.6-billion-year history, Sigurdsson said. "Now, if any of them have biota in them? We don't know," he said."Maybe we should go catch one and drill into it."
The powerful Large Synoptic Survey Telescope, which is scheduled to start observing the heavens from Chile next year, will probably spot about one interstellar object per month when it's fully up and running, Loeb added.
