Astronomy Day 2021

Posted by as Special Events

A celebration of International Astronomy Day in Victoria, BC, Canada was held on May 15, 2021 as a virtual online event, sponsored by the Friends of the DAO and RASC Victoria Centre. Hundreds of people attended this live-streamed 4-hour event through both Zoom and Youtube.

The program lineup

  • Dominion Astrophysical Observatory (DAO) Virtual Tour
  • Live Solar Viewing from the DAO with David Lee, Sid Sidhu & Chris Purse
  • Guest Presentation – “Fossils in our Galaxy” by Dr. Kim Venn, a specialist at UVic in observational stellar spectroscopy, and the chemo-dynamical analysis of stars in the Galaxy and its nearby dwarf satellites. Stars contain a fossil record of the chemistry of the Universe at the time and place where they were born. Stars formed early in the universe contain very low amounts of elements heavier than Helium, and astronomers call these stars ‘metal-poor’. They are the fossils of ancient star formation in the galaxy. By studying the most metal-poor of these stars, we can read that fossil record to learn about the origin of the elements and formation of the Galaxy. Dr. Venn discussed the recent results on the metal-poor galaxy, including newly discovered streams in the halo, very metal-poor stars found in the Galactic Centre, and metal-poor stars in the Galactic disk that orbit in the opposite direction.
  • University of Victoria Telescope Tour with Karun Thanjavur
  • Ask an Astronomer (or two) with Jason Beaman and Nathan Hellner-Mestelman, hosted by Amy Archer
  • Astrophotography Gallery with Marjie Welchframe, David Lee and friends featuring music from Vox Humana, Jeff Enns (composer)
  • Planetaruim Show from the CU – Draco & Hercules – Aaron Bannister & the constellation blanket
  • Live Stream from the Plaskett Telescope, the Centre of the Universe (CU) and other locations featuring David Lee, Dan Posey, Dave Payne, and Brock Johnston – the RASC Electronic Assisted Astronomy Group and hosted by Ruhee Janmohamed
Thanks to everyone who made this event a success!
