The James Webb Space Telescope is open, cooled down, and about ready to peer into the past. With its infrared sensors, Webb is capable of detecting the light from some of our universe’s earliest stars and galaxies. (With imaging equipment so sensitive, if bees lived on the moon, JWST could see them!) Light from these early stars and galaxies has been traveling for billions of years, just now reaching Earth. This allows us to see what stars and galaxies of the early universe looked like and how they formed! We will have to wait another couple billion years to know what they look like today. Hang in there JWST!
