851-Scientists Views Odds of Aliens

Author: Albert D. Grauer May 30, 2025 Duration: 2:01
In a recent paper published in Nature Astronomy entitled “Surveys of the scientific community on the existence of extraterrestrial life”  Dr. Peter Vickers and his team of 10 co-authors report the results  of their survey of the lead authors for the past 10 years in the top three astro-biological journals.  These researchers sought to measure if their sample group of scientists thought it likely that 1) simple life,  and/or 2 ) life more complex than terrestrial bacteria, and/or 3) Intelligent life comparable or superior to human beings exists outside of Earth.

Each episode of Travelers In The Night feels like a quiet, personal conversation under a dark sky. Hosted by astronomer Dr. Albert D. Grauer, this podcast brings the distant cosmos into sharp, intimate focus. Dr. Grauer isn't just an observer; he's an active participant in the hunt, working with the Catalina Sky Survey team that has consistently discovered near-Earth asteroids for years. In these brief and engaging segments, you'll hear firsthand accounts of what it's like to track these ancient celestial travelers-the asteroids and comets that silently pass by our world. The discussions move beyond simple facts to explore the real-world implications of these discoveries, from planetary defense to the sheer wonder of our dynamic solar system. Accompanied by the contemplative music of John Lyell's "Eternity," each installment offers a moment of calm reflection on humanity's place in the universe. It’s a perfect blend of grounded science and cosmic curiosity, making complex astronomical concepts accessible and deeply fascinating. For anyone who has ever looked up and wondered what's out there moving in the dark, this podcast provides a direct line to the front lines of discovery.
