Dark Sky Star Party (first clear night: Monday, Tuesday or Thursday) (CANCELLED)

See the Milky Way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light polution, there is so much to see. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window. Check our homepage for GO/NO-GO calls as this event is weather dependent.

DDO Astronomy Night: Methane on Mars: Fact, Folly, or Figment? with Dr. John Moores (ONLINE)

From the first announcement of its discovery in the atmosphere of Mars in 2003, methane has “punched above its weight” in our scientific imagination of the red planet. Because methane is quickly destroyed by the current chemistry active on Mars, it has to be supplied in the present day by some as yet unknown process. On the Earth, it is living systems that produce the abundant methane that we see in our atmosphere.
