What is the James Webb Space Telescope? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice explain the JWST and all the science behind it with the help of Chief NASA scientist Jim Green.

What is JWST looking for? Will it be a replacement for Hubble? We explore the different wavelengths of light and how JWST will let us peer into the past. Is JWST essentially a time machine? What sort of objects will it help us see? Can it track objects within our solar system? We break down where the telescope will be pointed first and where it will be launched to. How far away will the JWST be from Earth? What is L2 and where is it? Finally, we attempt (and fail) at getting over the excitement of launching something that has never existed before!
