In a galaxy far far away, a black hole and a big space rock walks into a bar.
The World is Your Telescope: Our first ever image of a supermassive black hole
On April 10 2019, Astronomers released the first image ever taken of a black hole – a supermassive beast lurking at the centre of galaxy M87. By discussing at the science and scientists behind the image, Toby will show why humankind cares about this amazing result and what more it can help us understand.
Is a big rock in space coming to destroy us all? The threatening, the nonthreatening, and the straight up make-believe
Ben K. D. Pearce (Ph.D. Candidate Physics & Astronomy - Astrobiology McMaster University)
Have you ever seen in the news, or heard from a friend, that a big space rock is going to hit or nearly miss the Earth? Maybe you've even heard stories of numerologists that regularly predict the precise date of the apocalypse. Should we be afraid for our lives and the future of humankind? I will answer these questions, by first distinguishing the big rocks in space that could potentially impact the Earth, from the ones that are unlikely to even come close; as well as the big rocks that exist in the Solar System, from the ones that are only make-believe.
