Stellafane, Mars, and Williamina Fleming
In the August 2023 issue of Sky & Telescope, we’re celebrating the 100th anniversary of the Springfield Telescope Makers with a brief history of the club and its famous annual star party, Stellafane. Then, we’re taking a look at E. E. Barnard’s photographic Milky Way atlas and observing some of Williamina Fleming’s little-known, deep-sky discoveries. Next, we’re reviewing the history of the Milky Way as told by the metallicity of its oldest stars. Finally, we celebrate NASA’s Insight lander which signed off for the last time at the end of 2022, but not before it provided a new perspective on the Red Planet’s interior.
Conquered by dust, the Insight lander has ended its mission after giving us an unprecedented look at seismic activity on the Red Planet.
