Quick Summary

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...
