If you have been online recently, you have surely seen the incredible pictures of deep space taken by the James Webb Telescope. Not only are these photographs beautiful, but they help us understand our universe in a deeper way.
NASA has been developing the James Webb telescope for decades, and it is currently millions of kilometres away from earth, exploring the deep reaches of space. You can go here to track it’s location.
As a successor the the Hubble telescope, launched in 1990, James Webb is allowing us to see the universe clearer than we ever have before.
Not only do we get to see the universe, but we are actually seeing back in time. Light travels at a constant speed, and takes a long time to reach us. This means that the further out in space we look, the further back in time we see. The James Webb telescope is powerful enough to see galaxies that were created about 100 millions years after the Big Bang. Essentially, this telescope is helping us discover the very origins of the universe itself.
