Avi Loeb

Harvard astrophysicist

Leads the Galileo Project, which builds telescopes to look for technological objects.

Loeb is a Harvard astronomy professor and former chair of its astronomy department. He has argued that the interstellar object 'Oumuamua may have been artificial, and in 2021 he started the Galileo Project to look for technology in the sky with purpose-built sensors.

In 2023 he led an expedition that pulled tiny spheres from the ocean floor near Papua New Guinea, where a meteor fell in 2014. Other scientists dispute his reading of the samples.
