Deb Haarsma visits the studio to talk to Jim about the James Webb Space Telescope and some of the first images that it has sent back to earth.
You don’t want to miss this episode, it’s full of fun facts and explanations of what we are seeing when we look at these images and how they were taken!
Had barely started reading the transcript when the talk about the telescope’s orbit got me curious. I found this
What an odd but obviously advantageous orbit. I guess the earth serves as a shepherding moon for it.
Better yet there is a good explanation in this one. How James Webb Orbits "Nothing" - YouTube
Here is a pic from the DSCOVR satellite which orbits the sun at L1 about a million miles from earth the other direction toward the sun. The James Webb is at L2.

If anyone wants a easy reading book on stars, I can’t recommend this book highly enough.
