James Webb's Infrared Sensitivity Gives Us a New Window to the Universe

With James Webb, that infrared sensitivity gives us the ability to look in places that were previously obscured. What I like most about James Webb is you get to see the birth of galaxies as well as far away and the birth of stars nearby. The Milky Way galaxy formed about 10 billion years ago. So if we're looking at galaxies 10 billion light years away, co-moving, then that means that we are looking at what our Milky Way galaxy probably looked like when it was just starting to form.
