Mysteries of the Universe: Black Holes, Dark Energy, and More: Fall Semester


Fifty years ago, humans landed on the Moon. We’ve since discovered countless planets orbiting other suns, and potentially habitable environments in our own solar system. We know how big the universe is, how old it is, and what’s it’s made of. But we also face mysteries: black holes, dark matter, and dark energy. We’ll cover everything you’ve always wanted to know but were afraid to ask. No math or science background required. You’ll also get to use a large telescope at a local observatory.


Meets at the Cambridge Center for Adult Education, 8 Tuesdays: Sept. 17 - April 2 - Nov. 5, 2019 - 7:45 PM - 9:15 PM.




 June Astronomy-Related Events in the Boston Area  



Thursday, June 13, 2019, 8:00 PM

Amateur Telescope Makers of Boston (ATMoB) Monthly Meeting

60 Garden St.

Cambridge, MA 02138

Topic and Speaker: "Library Telescope Program and Stonehenge", Kelly Beatty
Our guest speaker for the June meeting will be J. Kelly Beatty, MS. Kelly will update us on the status of the New Hampshire Astronomical Society’s Library Telescope Program and how ATMoB could play a role in expanding the effort. He is interested in creating thoughtful discussions on the topic as well as promoting the idea that ATMoB gets involved in the program. Kelly will also discuss his most recent trip to Stonehenge, tracking down the quarry where many of the stones were excavated to make up this pre-historic structure. Academics have suggested the site has possible connections with ancient astronomy as well as ritualistic purposes. Senior Editor Kelly Beatty joined the Sky and Telescope staff in 1974. From 2004-07 he served as the editor of Night Sky, their magazine for beginning stargazers. After 43 years of pounding the keyboard, in early 2018 he retired from full-time work. He remains actively involved in many Sky & Telescope articles, tours, and other projects. Kelly holds a Bachelor’s degree in geology from the California Institute of Technology and a Master's degree in science journalism from Boston University. During the 1980s he was among the first Western journalists to gain firsthand access to the Soviet space program. Asteroid 2925 Beatty was named on the occasion of his marriage in 1983, and in 1986 he was chosen as one of the 100 semifinalists for NASA's Journalist in Space program.

Kennedy Presidential Library and Museum, with Ambassador Caroline Kennedy, will host a day-long symposium highlighting the history that led to the first Moon landing, current scientific and technological space initiatives, and the future of space exploration. The program will challenge Americans to learn from the past, draw inspiration from President Kennedy’s vision, and renew our civic commitment to solving the great challenges of our own time. Attendees are asked to register for each panel separately. Please note that absolutely no backpacks or large bags will be permitted in the Library on June 19.

Scientists Maria Zuber, MIT Vice President for Research, Laurie Leshin, President, Worcester Polytechnic Institute, and Sara Seager, MIT Professor of Planetary Science and Physics, will discuss scientific discoveries that have changed our understanding of the universe beyond Planet Earth, and questions that still remain unanswered. CNN host S.E. Cupp moderates.
  2:45 PM - 4:15 PM Apollo: Missions to the Moon Screening
    Join us for a special preview of National Geographic’s latest documentary, Apollo: Missions to the Moon, airing in July 2019.
