The Physics of Meteors

See the Video! https://youtube.com/live/BFuW-zfH5RU

Avi Loeb joined Brian Keating after he led a Galileo Project expedition to the Pacific Ocean to retrieve spherules of the first recognized interstellar meteor, IM1. These samples were brought back to Harvard College Observatory over 50 spherules in total, which lay on the deep ocean floor for nearly a decade. These sub-millimeter-sized spheres, which appear under a microscope as beautiful metallic marbles, were concentrated along the expected path of IM1 — about 85 kilometers off the coast of Manus Island in Papua New Guinea. Their discovery opens a new frontier in astronomy, where what lay outside the solar system is studied through a microscope rather than a telescope. That 83% of the matter in the universe is apparently composed of dark matter which was not found yet in the solar system should teach us modesty in forecasting the nature of interstellar objects.
