Aliens

The question of whether we are alone in the universe has fascinated people for generations. At the SETI Institute, scientists pursue this question through focused, data-driven research, searching for technosignatures: signs of advanced extraterrestrial civilizations.

Dr. Sofia Sheikh, a radio astronomer at the SETI Institute, is part of the team leading this search. Her work explores how intelligent life might reveal itself through radio transmissions and what signals we might expect to detect. She also studies Earth’s own technological emissions to better understand how our planet might appear to observers light-years away.

Furthermore, using powerful radio telescopes and advanced software, SETI Institute researchers at the Allen Telescope Array (ATA) scan the sky for narrowband signals—frequencies that don’t occur naturally and could point to technology elsewhere in the universe. Their efforts involve sorting through massive datasets, filtering out interference, and applying machine learning to improve detection methods over time.

This work is both deeply technical and profoundly human. It challenges our assumptions about what life might look like, how it might evolve, and how we might one day recognize it.
