If intelligent life exists, why haven’t we heard from it? 👽 Astrophysicist Simon Steele from the SETI Institute puts it in perspective: If our solar system were the size of a quarter, the Milky Way would stretch across North America. A signal from an alien civilization 2,000 light-years away? It’s still on its way. #Space #FermiParadox #Astronomy #Astrophysics #Science #AlienLife (fb)

Are we alone in the universe or are we surrounded by worlds teeming with life? Astronomer and Deputy Director of the Carl Sagen Center for Research at the SETI Institute Simon Steele explains why the search for extraterrestrial life is far from science fiction. From oceans beneath icy moons to mysterious radio signals traveling thousands of light-years, the evidence suggests life might be far more common than we think. #Science #Space #Astrobiology #SpaceExploration #ExtraterrestrialLife (fb)
