909- 2026 JH2

Author: Albert D. Grauer July 24, 2026 Duration: 2:01
My Catalina Sky Survey teammates  Josh Hogan and Alessandra Serrano were asteroid hunting in the constellation of Ursa Major when they discovered a fast moving point of light in the night sky. My team the Catalina Sky Survey operates 5 telescopes on top of mountains near Tucson, Arizona except for the 3 nights per month when the moon is too bright.  Our goal is to detect an impacting object like 2026 JH2 in advance to warn people in the effected area to stay away from doors and windows.

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.
