Hamilton Amateur Astronomers: SETI: An Exploration of Space and Astronomy

Guest speaker Stephen Holmes writes: “I suspect we all wonder about alien civilizations. SETI, the search for extraterrestrial intelligence, and the Drake Equation set out some tools to help us get our heads around these huge numbers and consider realistically how plentiful or rare these civilizations are. Astronomy gives us the tools to determine realistically the star systems that might host these civilizations. Join me to consider some of these considerations.”

Dunlap Institute: Astronomy on Tap T.O. (CANCELLED)

We are sad to announce that, as a precaution to protect against COVID-19, we will be cancelling Astronomy on Tap for March 20. This was not an easy decision to make, but we decided that it was in everyone's best interests to err on the side of safety and caution.   Astronomy on Tap T.O. will, of course, continue this year and in the future - so please continue to check out Event Horizon, our website, and social media for those dates.

RASC, Mississauga Centre: Apollo 13 - The Flight That Failed (CANCELLED)

Due to the COVID-19 crisis and the suspension of in-person classes at UTM, we have cancelled this meeting. Fifty years ago, the third mission was launched to land two people on the Moon. On the third day of the flight, a problem occurred which cancelled the plans for the lunar landing and instead, started a race to get the astronauts home alive. In this talk, Randy Attwood will detail all the things which had to go right to save the Apollo 13 crew.
