834-Dark Comets

834-Dark Comets

Author: Albert D. Grauer January 31, 2025 Duration: 2:01
From our vantage point on planet Earth asteroids appear as moving points of light which strictly follow the law of gravity as they orbit the Sun. On the other hand comets appear as gas clouds which sometimes deviate from their gravitational orbits when they burp bursts of gases as they are warmed by the Sun. Dark comets appear as points of light like asteroids but move through space as though they are influenced by small rocket like bursts of volatile materials in cometary fashion.

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.
