TTC Video – Experiencing James Webb: The Invisible Universe Revealed

Join a noted astronomer as she presents the wonders of the universe through the matchless eye of the James Webb Space Telescope

The James Webb Space Telescope is a 21st-century marvel: the largest and most sophisticated space telescope ever built, operating over a million miles from Earth. By observing in infrared light, invisible to the human eye, Webb can discern the faint, ancient glow of the first stars and galaxies after the Big Bang; identify life-supporting gases in the atmospheres of planets orbiting other stars; and pull back the veil on star-forming regions hidden within thick clouds of interstellar dust. It is the most powerful astronomical tool ever built—and our deepest look yet into cosmic origins. In Experiencing James Webb: The Invisible Universe Revealed, astrophysicist Sarah Rugheimer presents a clear, engaging introduction to Webb’s science, engineering, and discoveries in 12 beautifully illustrated half-hour lectures. The course surveys Webb’s most important scientific findings and includes a full lecture on how to access Webb images online and experiment with free image-processing tools, learning how astronomers extract scientific meaning from raw data. You’ll also discover how Webb’s gold-coated segmented mirror functions as a single ultra-precise instrument, why the telescope operates a million miles from Earth in extreme cold, and how infrared astronomy lets us see the early universe as it was billions of years ago—making Webb, in effect, the ultimate time machine.
