'INTERSTELLAR': Does this Harvard scientist have proof of alien life?

Fox News on Youtube has the story.

Harvard's Dr. Avi Loeb joins 'Fox News Saturday Night' to discuss finding hundreds of tiny metal fragments apparently not from our solar system.

An interstellar object is an astronomical object (such as an asteroid, a comet, or a rogue planet, but not a star) in interstellar space that is not gravitationally bound to a star. This term can also be applied to an object that is on an interstellar trajectory but is temporarily passing close to a star, such as certain asteroids and comets (including exocomets). In the latter case, the object may be called an interstellar interloper.

The first interstellar objects discovered were rogue planets, planets ejected from their original stellar system (e.g., OTS 44 or Cha 110913−773444), though they are difficult to distinguish from sub-brown dwarfs, planet-mass objects that formed in interstellar space as stars do.

The first interstellar object which was discovered traveling through the Solar System was 1I/ʻOumuamua in 2017. The second was 2I/Borisov in 2019. They both possess significant hyperbolic excess velocity, indicating they did not originate in the Solar System. The discovery of ʻOumuamua inspired the identification of CNEOS 2014-01-08, also known as the Manus Island fireball, as an interstellar object that impacted the Earth. This was confirmed by the USA Space Command in 2022 based on the object's velocity relative to the so-called Sun. In May 2023, astronomers reported the possible capture of other interstellar objects in Near Earth Orbit (NEO) over the years.
