The sun never changes—or just about never. A few billion years ago it was much dimmer than it is today and a few billion years in the future it will be much brighter, but that’s a long time to wait if you want to see it change. Day-to-day and year-to-year the sun is pretty reliable.
But some other suns, a few peculiar stars scattered across the galaxy, pulse bright and dim like alien clockwork. They are called variable stars. If Earth lived near one of them, it would be cataclysmic. It would freeze into a snowball then burn to a cinder every other day, or week, or month—forever.
Some variable stars, for example, swell and shrink on fantastic scales while other erupt with enormous flares like sun-sized lighthouses scattered across the sky. As of 2021, nearly 50,000 of these bizarre stars have been found, many in our own stelar neighborhood.
On Wednesday evening, February 17, at 7:30, the Martz-Kohl Observatory will present another in its popular monthly series of special Zoom-conferences, this one on Variable Stars. The speaker, Donn Starkey, is an avid amateur astronomer who has made major scientific contributions in astronomy and astrophysics, authoring more than 70 research publications in astronomy. Donn believes astronomy is for everyone and enjoys bringing the stars down to earth to inspire and delight us all.
Donn Starkey’s presentations are geared for the general public who appreciate the beauty of the night sky and are interested in science.
To attend, simply go to www.martzobservatory.org and click on the program title starting at 7:15 to be on time for the 7:30 program. Meet the rest of the audience, and be prepared to be amazed and entertained. A lively Q&A time always follows each program.
Though the observatory remains closed for tours and in-person programs until the Covid-19 pandemic regulations allow safe reopening, important work continues.
In the spring work will be finalized for remote operation of the telescopes by members and cooperating observatories and educational institutions across the country and around the world. As a result, even if some Covid restrictions remain in place, members can return remotely to enjoy and use much of what MKO has to offer.
