The article “We Have 25 Spherules from IM1’s Site!” by Avi Loeb discusses the retrieval of 25 spherules from the site of the first recognized interstellar meteor, IM1. The spherules, which are being kept in vials for analysis, were collected from the ocean floor using a 200-kilogram magnetic sled. The total mass of the spherules is estimated to be about 30 milligrams, which is a tiny fraction of the estimated 500 kilograms of material that was part of the IM1 fireball. The article emphasizes the significance of this achievement, as it marks the first opportunity for astronomers to study interstellar space using a microscope instead of a telescope. Future analysis of the spherules could potentially reveal whether their composition is natural or technological in origin, which could have profound implications for our understanding of the universe.
