<p><strong>Hotel Mars Dr. Paul Kalas for Weds, Jan. Jn. 28, 2026, #4495</strong></p><p><strong>Quick Summary</strong></p><p>John Batchelor and I presented Professor Paul Kalas of the University of California at Berkeley, who discussed his groundbreaking observations of the Fomalhaut star system using the Hubble Space Telescope. Kalas explained how he discovered evidence of asteroid collisions creating massive dust clouds, which occur approximately every 100,000 years and last only 5-10 years. The discussion explored how planetary systems form through collisions between smaller objects, with Fomalhaut serving as a “time machine” to Earth’s early history when similar collisions shaped our own solar system. The conversation concluded with a broader discussion about the uniqueness of our solar system and the ongoing search for Earth-like planets around other stars, with David Livingston and Dr. Space highlighting their show’s focus on both space science and commercial space development.</p><p><strong>Detailed Summary</strong></p><p>Professor Paul Kalas from the University of California at Berkeley discussed his recent discovery using the Hubble Space Telescope of a star system called Fomalhut Dr. Pau, which is 25 light years away. He explained how they used techniques to cancel out the star’s bright light and revealed the presence of dust belts and a planet with a ring system, initially thought to be similar to Saturn. However, a new point of light appeared in 2023, challenging their previous understanding of the system, as planets are not supposed to suddenly appear.</p><p>Dr. Kalas discussed the formation of Earth and the moon, explaining that a collision with a Mars-sized object created the moon and that Earth was subject to frequent impacts during the Great Bombardment. He mentioned ongoing research into a debris belt around a star 25 million light years away, suggesting a planet might be responsible for the belt’s structure. Our guest said his colleagues have imaged the star with the James Webb Space Telescope but have not yet detected any planets as large as Jupiter. He noted that smaller planets, like Uranus and Neptune, might exist but are beyond current detection limits.</p><p>This was a one segment Hotel Mars program but after Dr. Kalas spoke, John talked with me about The Space Show, Hotel Mars and more.
