Nobel Physics Prize laureate, Dr. John Mather, explains how the early cosmos (whose precise characteristics he helped pin down) became our present-day universe of galaxies, stars, and planets. Dr. Mather is the Project Scientist for the James Webb Space Telescope (which will be a much larger instrument than the Hubble when it is launched in late 2021). He also discusses the history of the Webb telescope and how it is designed, and then suggests some of the exciting things this telescope will be able to do. This was the Feb. 2021 Silicon Valley Astronomy Lecture.
