You may have noticed that the names of Uranus’ moons are familiar. That's because they are named for fairies and sylphs from the works of William Shakespeare and Alexander Pope. 📚

While the Martz 24" Dall-Kirkham telescope is being upgraded for automated use, the Kohl 20" Cassegrain telescope is getting good use! Board member, Tom Traub, took this image of Jupiter and one of its moons, "Io," in October. The 2nd image is of Comet 67P/Churyumov-Gerasimenko, one of the best-studied comets. The European Space Agency’s Rosetta spacecraft rendezvoused with it in 2014. It has it's closest approach to Earth this year in early November.
Rosetta was the first mission ever, in August 2014, to orbit a comet’s nucleus and land a probe on its surface. It was also the first spacecraft to fly alongside a comet as it head towards the inner Solar System, watching how a frozen comet is transformed by the warmth of the Sun.
So cool.
Brownie troop 20137 visited the observatory in October. Do you have a group such as scouts, school classes or clubs? Check out the Martz-Kohl Observatory for guided tours or classes around Astronomy, Space and Physics. More info on our website: martzobservatory.org/ 👍🔭✨
REMINDER: This Saturday, October 16, 2021, starting at 7:00 PM at the observatory: Dr. Lynn Cominsky will present "Spacetime Symphony: Gravitational Waves and Black Holes" followed by videos and activities oriented around "International Observe the Moon Night." There will be 2 door prizes of NASA's graphic novel "First Woman" - about the first woman on the Moon and her trusty robot. The book is suitable for pre-teens and teens with an interest in Space or STEAM (Science, Technology, Engineering, Art, Science). More info on the observatory website: martzobservatory.org/ Face masks are required at all times at the observatory.
Fascinating article about Nuns mapping 480,000+ stars with an associated list of resources and activities for all ages. Check out the post!More than a century after they mapped over 481,000 stars, four once nameless nuns were at long last recognized for their many years of hard work at advancing human understanding of the universe! Sisters Emilia Ponzoni, Regina Colombo, Concetta Finardi and Luigia Panceri were recruited by the Vatican to measure and map stars as part of one of the greatest scientific undertakings of the late 19th century -- the vast international effort to map the entire night sky and create a comprehensive star atlas called the Astrographic Catalogue. Although this photo of the nuns had appeared in books about the history of astronomy, the women's names were never known until just a few years ago when Father Sabino Maffeo, a Jesuit priest who works at the Vatican Observatory, discovered their identities while organizing papers in the archive.
This grand project to map the sky first began in April 1887 when 56 scientists from 19 countries decided to use the new discipline of astrophotography to create photographic plates of the stars. Twenty observatories around the world participated in analyzing the 22,000 glass plates -- and, in many countries, while male astronomers directed the programs, women did of the labor-intensive work of processing and cataloging the stars. One of the most famous groups was the young women hired by Harvard Observatory director Edward Charles Pickering -- known as the "Harvard Computers," the group included such now famous astronomers as Annie Jump Cannon, Henrietta Swan Leavitt, and Williamina Fleming. However, the vast majority of women who worked for years on the project at observatories around the world who were never recognized for their contributions to astronomy.
Ultimately, the project resulted in a 254-volume catalog of 4.6 million stars. Although it was ultimately only half completed -- astronomers stopping work on the initiative in 1962 -- the Astrographic Catalogue became the basis of the star reference system used today. And, as Erin Blakemore observes in Smithsonian, "Though the women didn’t end up counting all of the stars, perhaps one day history will do a better job of counting the women whose diligent work helped map out the starry skies."
For picture books about several of the extraordinary women involved in early star mapping work as "Harvard Computers," we highly recommend "She Caught the Light: Williamina Stevens Fleming: Astronomer" (www.amightygirl.com/she-caught-the-light), “Look Up!: Henrietta Leavitt, Pioneering Woman Astronomer" (www.amightygirl.com/look-up), and "Annie Jump Cannon, Astronomer" (www.amightygirl.com/annie-jump-cannon-astronomer), all for ages 5 to 9
For more children's books about women who helped unlock the mysteries of the skies, check out "Listening to the Stars: Jocelyn Bell Burnell Discovers Pulsars" (www.amightygirl.com/listening-to-the-stars), "Always Looking Up: Nancy Grace Roman, Astronomer" (www.amightygirl.com/always-looking-up), "The Stuff Between the Stars: How Vera Rubin Discovered Most of the Universe" (www.amightygirl.com/the-stuff-between-the-stars), all for ages 5 to 9
For a fun activity book about female astronomers and astronauts which includes a variety of space-themed STEM projects, we recommend "Gutsy Girls Go for Science: Astronauts" for ages 8 to 11 at www.amightygirl.com/gutsy-girls-astronauts
For two fun dolls for aspiring young astronomers, we recommend the Astrophysicist Doll for ages 3 to 7 (www.amightygirl.com/astrophysicist-doll) and the Astronomer Lottie Doll for ages 3 to 8 (www.amightygirl.com/stargazer-lottie-doll)

For observing Indigenous Peoples' Day, it’s uplifting to read about Mary Golda Ross. 👍 🔭Have you heard of Mary Golda Ross? Born in 1908, she was a member of the Cherokee Nation. A "hidden figure" of America's space age, she also helped author the 'NASA Planetary Flight Handbook Vol. III' about travel to Venus and Mars. On this Indigenous Peoples' Day, learn more about Ross: go.nasa.gov/2NJ8USN

Participate in the International Observe the Moon Night at the Martz-Kohl Observatory on Saturday, October 16, 2021. "Observe the Moon Night" is a worldwide public event that encourages observation, appreciation and understanding of our Moon and its connection to science, exploration, and human culture. This annual event connects scientists, educators and night sky enthusiasts from around the world.
This event will be held in-person at the Martz-Kohl Observatory and starts about 8:45pm. Activities will begin after a special presentation, "Spacetime Symphony: Gravitational Waves and Black Holes" by Dr. Lynn Cominsky from 7:00pm to 8:30pm. Activities will include a tour of the observatory, videos about various aspects of the Moon: creation, composition, phases and myths/creation-stories as well as the showing and discussion of images of the Moon taken at the observatory.
For these two events, vaccinations and masks are required.
More info can be found at the Martz-Kohl Observatory website: martzobservatory.org
