JWST is particularly exciting because it’s our most sensitive infrared scope ever. Because of red shift (faster an object moves away from you redder it appears) objects in the early universe, or the most distant objects we can measure are only perceptible in infrared. They have theorized what will be there but this is our first real look at it. It’s exciting because we could either confirm the current theory or we might be surprised and have to go back to the drawing board.
