Astronomy Minute
Learn the basics of astronomy in one-to-two minute packets of concise information about specific topics. You are a busy person with a short attention span, and you want to learn about astronomical topics in a short amount of time. Your host Professor Ata is a PhD research astronomer and astrophysicist and a noted authority on stellar and galactic astronomy. I welcome your feedback at ata.sarajedini@gmail.com. See the web site astronomyminute.org for more. The podcast logo is courtesy of Zachary Greathouse and shows a globular cluster photo taken by the author with the Hubble Space Telescope.
