How a gold-coated mirror is unfolding the secrets of the cosmic dawn
In short: Nobel Laureate John C. Mather explains the engineering marvel of the James Webb Space Telescope and how its massive, origami-like design allows us to peer into the early universe.
The video follows the inside story of the Webb's design, construction, and launch. Mather describes how the telescope uses a 21-foot, gold-coated mirror and a sunshield the size of a tennis court to observe the first galaxies formed during the period known as cosmic dawn. By looking through clouds of gas and dust, the telescope aims to reveal star formation and investigate potentially life-bearing worlds like Titan and Europa.
Beyond the technology, the documentary explores Mather's personal journey, including his decades-long leadership of the NASA science team and the moment he received the call regarding his 2006 Nobel Prize in Physics.
