Upcoming events at U of T

November 17: Planetarium shows: New Horizons of Exploration

For thousands of years, humans have studied the heavens from the confines of the Earth.  In the last century, however, we have begun sending both people and machines to other worlds. Where have we gone, and what discoveries have we made? This planetarium show will delve into the history of space exploration, from the first tentative steps made during the Space Race to the first-ever flyby of Pluto by the New Horizons spacecraft and the ongoing mission of the Juno probe to study Jupiter.

November 24: ASX Talk: The quest for 1%: the past, present and future for measuring the Hubble Constant and the expansion of the Universe

Almost a century ago, Edwin Hubble discovered that galaxies appear to be moving away from us and that farther galaxies moved at faster rates. Hubble had discovered the expansion of the Universe and ever since, astronomers have been trying to better measure the rate of that expansion, quantified in a number called the Hubble constant. , using numerous standard candles.

Join U of T astronomy professor Hildig Neilson as he describes the history of measuring the Hubble constant: from some of the great arguments, to the discovery of “standard candles”, to the paradigm shift initiated by the Hubble Space Telescope Key Project. He will explore the future of measuring the Hubble constant to 1% precision–an achievement that will shed new insights into dark matter and dark energy.

Weather permitting the talk will be followed by telescope observations at 9:00pm at the top of the McLennan Physical tower. No registration is required and this event is open to everyone!

December 1: AstroTour: On Pulsars: Ultra Dense Material Spinning Dizzyingly Fast

Pulsars are magnetized spinning neutron stars that emit a beam of radiation. Since the first pulsar was discovered in 1967, thousands have been detected, and they continue to be one of the most interesting objects in the sky.

Join U of T astronomy graduate student Nikhil Mahajan as he describes the history of pulsar astronomy, the reasons why we care about pulsars, and where research may lead in the future.
