How Does The James Webb Space Telescope Work?

posted by Jason Kottke   Jan 19, 2022

The James Webb Space Telescope is still winging its way to its permanent home at the L2 point1 about 930,000 miles from Earth — it’s due to arrive in about 4 days. It’s a massive and fascinating project and for his YouTube series Smarter Every Day, Destin Sandlin talked to Nobel laureate John Mather, the senior project scientist for the JWST, about how the telescope works.

Also worth a watch is Real Engineering’s The Insane Engineering of James Webb Telescope:

It really is a marvel of modern science & engineering — I can’t wait to see what the telescope sees once it’s fully operational.
