Come to Henrietta Hankin Branch Library on Thursday, September 12th, from 6:30-7:30 for a fascinating presentation on the lifecycle of stars by Don Miller, PhD. “Celestial Journeys: the lifecycles of stars” will give an overview of the journeys of stars from birth through adulthood, to old age and eventual death. Stars experience the same familiar progression as other life forms but on a much different timescale. They live long lives, by human standards, converting hydrogen into helium and perhaps other elements if the star is of sufficient mass. We will learn about the various ways that a star can die. Some go out with a beautiful cloud of gas while others literally go out with a bang. Our own sun will eventually swell and perhaps engulf the Earth before it ends its lifecycle as a white dwarf.
Special focus will be given to T Corona Borealis, nicknamed the Blaze Star, which is about to put on a rare stellar display due to stellar aging. The Blaze Star can be seen currently in our northern sky. It appears as one star when in actuality it is two stars. One star has already ended its life and is sucking material from the still living sister star. Eventually, this will lead to an explosion which will make T Corona Borealis suddenly appear in the sky, visible to the naked eye. Learn how and when you may be able to observe this unique event!
Don has been interested in science and the stars ever since he had a night out with his father at age 6 looking at the sky and discussing the possibilities of the universe. He followed every aspect of the Apollo and subsequent programs. He saved up his money as a young kid to purchase an 8-inch reflector telescope and later as an adult moved on to an even larger telescope. He can frequently be found in his backyard or at star parties looking at the stars and sharing his love for space with the community. He has been a member of the San Francisco Sidewalk Astronomers, moved to Pennsylvania and joined the Chester County Astronomical Society, traveled to Wyoming to see the total solar eclipse, traveled to northern Sweden to see the northern lights, and many national parks for their dark skies, plus great hiking.
Dr. Don Miller is retired from a career in pharmaceutical research and can now devote his time to serving as a NASA Solar System Ambassador giving talks like this one to all age groups about astronomy, NASA programs and space in general. He also participates in the Astronomical Society of the Pacific’s Project Astro which brings hands-on space science to grade school children.
We are most honored to have Don speak at the library and hope you can join us for this most illuminating presentation.
