Author: Albert D. Grauer December 9, 2025 Duration: 2:01
At about 2AM on July 18, 2011 several people in near Tata, Morocco saw a bright fireball which was described by one of them to be initially yellow, then turned green, and finally exploded into several pieces producing two sonic booms. In October of 2011 desert wandering nomads began finding very fresh looking dark fusion-crusted stones which were radioactively dated by Dr. John Duke of the University of Alberta to be less than 5 years old. In total 15-24 lbs of meteorites consistent with a very recent fall were found in a strewn field, were whisk away to receive high prices from collectors, and named after the town of Tissint [tee.seent] about 30 miles from their discovery location.

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.
