Скачать или смотреть Are We Alone in the Universe? SETI’s Simon Steel & the Search for Life

Are we alone in the universe or are we surrounded by worlds teeming with life?

Simon Steel, astronomer and Deputy Director of the Carl Sagan Center for Research at the SETI Institute, explores one of humanity’s most profound questions: Where else could life exist? From Mars’ ancient oceans and possible fossil remnants, to the vast hidden seas beneath the icy crusts of Jupiter’s and Saturn’s moons, the potential homes for life are everywhere we look.

Beyond our solar system, nearly every star in the night sky may host planets. That’s billions of worlds, each with its own story, climate, and possibility for life. Could some of them be alive right now?

The SETI Institute is dedicated to the search for extraterrestrial intelligence. Steele explains how scientists listen for faint radio signals that could have traveled thousands of years across space, how they detect biosignatures like oxygen in alien atmospheres, and why the distances involved make communication with other civilizations incredibly challenging.

Along the way, we learn that looking for life is also about looking inward: understanding how Earth formed, how microbes shaped our atmosphere, and how humanity fits into the vast system of the cosmos.

Steele reminds us that finding life, whether microbial or intelligent, would be a discovery for all of humanity. It would reshape our understanding of the universe and our place within it.

With over 25 years of experience in education, science communication and public outreach, astrophysicist Dr. Simon Steel bridges the gulf between the complexities of modern space science and the public fascination with the wonders of the Universe. An award-winning lecturer and teacher, Simon has presented on all aspects of the cosmos, from black holes to aliens to Stonehenge, at museums, universities, NASA centers and aboard cruise ships. As part of the SETI Institute Outreach team, he regularly hosts the online science magazine SETI Live and has represented the Institute at business, consular and industry events worldwide.

Simon is Deputy Director of the Carl Sagan Center for Research at the SETI Institute. As an observational astrophysicist, he specialized in optical spectrophotometry, with an interest in the star formation histories of galaxies. Simon has held lectureships at Harvard University, University College London and University College Dublin, and is an eight-time recipient of Harvard’s Certificate of Distinction in Teaching award for undergraduate education. Originally from England, Simon is a qualified science teacher, Fellow of the Royal Astronomical Society and member of the International Astronomical Union.

Among the world's largest science centers, the Museum of Science engages millions of people each year to the wonders of science and technology through interactive exhibitions, digital programs, giant screen productions, and preK – 12 EiE® STEM curricula through the William and Charlotte Bloomberg Science Education Center. Established in 1830, the Museum is home to such iconic experiences as the Theater of Electricity, the Charles Hayden Planetarium, and the Mugar Omni Theater. Around the world, the Museum is known for digital experiences such as Mission: Mars on Roblox, and traveling exhibitions such as the Science Behind Pixar. Learn more at https://www.mos.org/
