Would you like to know more about the night sky and what we can see? We welcome you to join us (via Zoom) once a month for a low intensity 45 minute presentation followed by Q&A. It’s ok if you missed the previous session, they’re mostly self-contained.

  • Moon, Sun, and planet cycles
  • Explore the Universe Certificate
  • Eyes, binoculars, telescope basics
  • Star clusters, craters on the Moon, comets
  • Rings of Saturn, Jupiter’s clouds and moons
