The James Webb Space Telescope's Redshift
A telescope of this magnitude actually isn't taking pictures of the present. It's taking photos of the past. Can you explain why that is? And then you also mentioned the thing about redshift.

But a couple of folks might be saying, well, wait a minute, how is the telescope telling us what happened in the past? What is it that about the images that suggest we can know what happened way, way back versus what's going on right now? I think a picture of something.
