Asteroid Hunters – IMAX Theatre (admission applies)

Narrated by Daisy Ridley (Star Wars), Asteroid Hunters ventures into deep space for a fascinating look at asteroids, their cosmic origins and the potential threat they pose to our world.

Written and produced by Phil Groves, produced by Jini Durr and directed by W.D. Hogan, Asteroid Hunters introduces asteroid scientists – the best line of defense between Earth and an asteroid’s destructive path – and reveals the cutting-edge tools and techniques they use to detect and track asteroids, and the technology that may one day protect our planet. The effects of an asteroid impact could be catastrophic and while the current probability of an event in our lifetime is low, the potential consequences make the study of asteroids an incredibly important area of scientific research. Witness the latest in planetary defense and how science, ingenuity and determination combine to explore the world’s most preventable natural disaster.

Asteroid Hunters has a run time of 38 minutes and is presented by IMAX here in Victoria in association with Huahuang Pictures.

Video transcript of the meeting

Deborah Lokhost presented to us about the Dragonfly Telephoto Array. She is an Instrument Science Research Associate at the NRC Herzberg Astronomy and Astrophysics Research Centre in Victoria, BC. During her PhD in the Department of Astronomy and Astrophysics at the University of Toronto, she worked with the Dragonfly Telephoto Array to observe and study galaxies. She designed an upgrade to Dragonfly and built a pathfinder telescope based on this design which she then used to study gas in the surroundings of galaxies. She is currently leading the construction of a full-scale upgrade to the telescope which has the ultimate goal of imaging gas in the “cosmic web” of dark matter.

Dragonfly Telephoto Array

  • Reasons for Dragonfly
    • Large galaxies with low luminosity (surface brightness)
    • Light scattering is the main problem
    • Reflecting telescopes don’t help, since they scatter light
    • Refractors have a limit in size
  • Design
    • Canon using nano coatings to reduce light scatter for their long telephoto lenses
    • Using 48 Canon EF 400mm f/2.8L – split between two Paramounts/observatories
    • Mexico Skies Observatory – site
    • Astroplanner – mission planning and execution
    • Been in operation for 6 years
    • Comparison between Dragonfly and Sloan Digital Sky Survey
    • Diffraction Limited SBIG CCD cameras
    • Intel stick computers talk to a master computer for data collection
    • Filter 1/2 G and 1/2 R (Sloan clone)
  • Science
    • Main target is galaxies
    • What is Dark Matter? 90% of the Milky Way is Dark Matter
    • Dark Matter first detected by Vera Rubin
    • Ultra Diffuse Galaxies – new discovery by Dragonfly team
    • Looking for Globular Clusters in these ultra diffuse galaxies
    • First field images – Coma Berenice cluster of galaxies
    • NGC 1052 diffuse galaxies – very little Dark Matter – unusual!
    • Modified Newtonian Galaxy – alternate theory to Dark Matter
  • What about outside galaxies? – Deborah’s main study
    • Detecting faint gas emissions using ultra-narrowband filters
    • Simulated Ha observations from EAGLE cosmological simulation that should be possible using Dragonfly
    • Mounting the ultra-narrowband filters in front of the lenses would improve the result, and tilting the filter improves performance
    • Discovered a new Ha shell around M81/M82
    • 0.8nm filters will be used on new array
    • 30 new lenses to start with for testing and fine tuning
