Avi Loeb, a former chair of the Harvard Astronomy Department, claims to have found fragments of an interstellar meteor, referred to as "IM1," in the Pacific Ocean. His expedition retrieved tiny metallic spheres, or spherules, which he believes are evidence of the first-known interstellar meteor.

However, the scientific community is divided on his claims. Some experts argue that the data and methodology used are not robust enough to support an interstellar origin for the meteor. Despite the criticism, Loeb is pressing forward with analyses of the spherules.
