390E-427-Meteor Whispers

Author: Albert D. Grauer May 26, 2026 Duration: 2:01
Often observers report hearing a percussive sound, like a sonic boom from an aircraft, minutes after viewing a bright meteor fireball. In addition, in a fewer number of instances, there are many reliable reports of observers hearing popping, hissing, and rustling sounds at the same time they are observing a very bright meteor traveling though the night sky. Professional astronomers have long dismissed these reports saying that what these people hear simultaneously with their visual observations cannot be due to to sound traveling from the meteors path since sound travels 800,000 times slower than light and would take 1.5 to 4 minutes to traverse the distance that the light does in a tiny fraction of a second. Recent scientific studies have begun to shed light on the interesting mystery of how the small number of what we now call electrophonic meteors produce simultaneous light and sound. One theory is that the flickering bright light produced in the meteor's path is absorbed by by hair or other material near the observer's ears producing acoustic sound waves. An alternate hypothesis is that as the meteor streaks through our atmosphere it ionizes air molecules whose motion in the Earth's magnetic field generates radio waves which travel to objects near to the observer causing them to vibrate and thus produce sound. Either way observers with large amounts of hair or those near metallic objects like barbed wire fences are the most likely to hear these strange unusual sounds. If you are lucky you could hear a meteor's dying whispers and could even be the first person to record these sounds on your cell phone. For Travelers in the Night this is Dr. Al Grauer.

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.
