Author: Albert D. Grauer June 23, 2026 Duration: 2:01
Asteroids appear as moving points of light in an asteroid hunter's images so that when my Catalina Sky Survey teammate Alex Gibbs spotted a fuzzy moving object he immediately suspected it to be a comet. The data obtained by astronomers over the next 8 days enabled scientists at the Minor Planet Center to verify Alex's 31st comet discovery and give it the name C/2018 A6 (Gibbs). In January of 2018 it was in the constellation of Leo traveling from the vast empty space above the Sun's north pole toward the plane of the solar system which contains all of the planets and most of the asteroids. In March of 2018 Comet C/2018 A6 (Gibbs) will cross the plane of the solar system a bit farther from the Sun than the giant planet Jupiter's orbit. After that it will continue on a wide arcing parabolic path, pass under the Sun's south pole in the summer of 2019, and once again cross the plane of the solar system in February of 2021. After that it will continue into the vast empty space above the Sun's north pole from whence it came. How a comet brightens as it approaches the Sun is difficult to predict. With luck humans will be able to spot Comet C/2018 A6 (Gibbs) with their naked eye, binoculars, or a small telescope as it pays a rare visit to our planet's neighborhood.

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.
