The Latest News & Upcoming Events

October's meeting

Through presentation of Edwin Hubble's galaxy classification scheme, John will talk about galaxy morphology, composition, and evolution. John also plans to investigate the issue of why the various types of galaxies look like they do, including discussing recent research and theories. He will also tracing how some ideas about galaxies have changed over the past seventy-or-so years. He will also point out how some galaxies that have led righteous lives have halos, whereas others that have gone over to the Dark Side are full of Dark Matter (hey, a little humor never hurts!). John will bring along his copy of Arp's "Atlas of Peculiar Galaxies" in its original 1966 format (published as a supplement to the Astrophysical Journal), as well as his copy of the Allan Sandage's "Hubble Atlas of Galaxies." John is hoping for not just questions, but also input from the members as regards to the various theories of galaxy morphology and evolution.

John Martin, a retired attorney, has had a lifelong fascination with and interest in astronomy. As a child, he attended meetings with the St. Petersburg Astronomy Club, and has since belonged to a variety of astronomy organizations in California, including the High Desert Astronomical Society in San Bernardino County (where he served a Program Director and Vice-President), and the Astronomical Society of the Pacific. Since early youth, Mr. Martin has tenaciously pursued everything Galaxy, and he closely follows the ever-changing theories and improved understanding regarding galaxy formation, composition, change, and demise. To further his knowledge of galaxies, John has read voraciously, including Astrophysical Journal articles and papers from International Astronomical Society galaxy symposia, and he has also taken courses in Physics and Quantum Physics.
