The NASA Kepler Spacecraft has discovered more than 2,000 planets which have been confirmed to be orbiting distant stars. It performs this remarkable feat by imaging more than 145,000 stars simultaneously to observe and measure the tiny dips in light which occur as a planet passes in front of its star. Astronomers have long known that many of the solar systems in the Milky Way have more than one star. To investigate the possibilities for life in a double star system, Dr Max Popp a scholar at Princeton University and Dr. Siegfried Eggl of Germany's Max Plank Institute substituted the real giant planet orbiting the stellar pair Kepler 35A and B with an Earth sized one orbiting the Kepler AB pair with periods between 341 and 380 days. Their detailed analysis is published in the journal Nature Communications.

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.
