Key Takeaways:

The James Webb Space Telescope has successfully completed its deployment and is on its way to its final destination—1 million miles away from Earth.

Webb has been under close watch around the globe, as the world’s most powerful telescope unfolded itself in outer space this weekend. In a joint effort between NASA, the European Space Agency (ESA), and the Canadian Space Agency, Webb will look into the most distant galaxies in the observable universe.
