881-Dangerous Comets

881-Dangerous Comets

Author: Albert D. Grauer January 9, 2026 Duration: 2:01
It is possible the object creating the Tunguska event in Russia 1908 which knocked down 80 million trees over an area about twice the size of New York City was a fragment of a comet or asteroid. The International Asteroid Warning Network 2025 campaign to track Comet 3L/Atlas prepares the worlds observatories for the eventual time when a comet fragment has our number on it.

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.
