The James Webb Space Telescope (JWST), which launched in 2021 and began science operations in 2022, will peer into the past to find the first objects that formed after the Big Bang, the first black holes, the growth of galaxies, the formation of stars and planetary systems, and more. 100 times more powerful than the celebrated Hubble Space Telescope, JWST could observe a 1 cm² bumblebee at the Earth-Moon distance, in reflected sunlight and thermal emission and promises to reveal more wonders of our universe.
In this lecture, senior project scientist for JWST and Nobel Prize-winning astrophysicist John C. Mather will discuss how NASA and its partners built JWST and share some of the telescope’s first discoveries.

This program will be presented in-person at the Steven F. Udvar-Hazy Center in Chantilly, Virginia, and will be streamed on YouTube with live closed captioning.
