The New Golden Age of Astronomy: Hubble's Universe Today

Barely a century ago, the great Carnegie Science astronomer Edwin Hubble became the very first person to confirm the existence of galaxies beyond the Milky Way. Five years later, he went on to show that not only was the universe infinitely more immense than previously thought, but that it was also expanding. Hubble's two extraordinary discoveries form the bedrock of modern astronomy.
In the first Neighborhood Lecture of 2025, Carnegie's recently appointed President, Dr. John Mulchaey, will explore how observations since the time of Hubble have helped redefine our entire understanding of the universe — from the existence of dark matter and supermassive black holes to planets around other stars.
