Is the Milky Way galaxy teeming with alien creatures, or is Earth unique in its ability to host life? It’s a question astronomers are still unable to answer. 

But we are closer than ever before to knowing whether life is the exception or the rule: since the 1990s, more than 4,000 planets have been discovered beyond our solar system. At a Perimeter Institute public lecture on November 6 at 7 p.m., astrophysicist and author Elizabeth Tasker took her audience on a tour of a few of the worlds we’ve found in the galaxy — and considered whether someone (or something) else may call them home.

The Perimeter Institute’s public lectures are usually held once a month. TVO.org will stream the entire 2019-20 series.
