Gresham College | A Mirror in the Sky - Chris Lintott @GreshamCollege | Uploaded September 2024 | Updated October 2024, 4 days ago.
The first lecture in the series considers the most famous telescope of all, the Hubble space telescope. A project more than forty years in the making, Hubble overcame an initial disaster with a misshapen mirror to drive a revolution in every part of astronomy, providing iconic views of everything from a comet crashing into Jupiter to a surprisingly vibrant, distant Universe. This lecture focuses in particular on what Hubble has revealed about the life - and death - of stars.
