Galaxies: Inside the Universe’s Star Cities
Saturday 9th February 2019: Session Three
On October 4, 1923, Edwin Hubble captured an image of the spiral nebula in Andromeda. To his surprise, he found a variable star that demonstrated the nebula was actually a distant system of stars and gas. He discovered the nature of galaxies and set the distance scale of the universe. Since that time, astronomers have found that 100 billion or more galaxies inhabit the cosmos, and they show a wide range of properties. David Eicher will summarise the current state of knowledge about galaxies in this illustrated talk. The work reflects content from his forthcoming book, Galaxies, to be published by Penguin Random House in spring 2020.
