Scores of unnamed galaxies you see here actually emitted their light more than 13 billion years ago, mere cosmic moments after the Big Bang. Thus, “we are going back further” explained Bill Nelson the Nasa Administrator when the president of the USA, Joe Biden was showed the sharp picture.

This one image and the countless others that come have been the result of more than 2 decades of focused efforts by a collaboration between the world’s greatest scientists and engineers from NASA, ESA and CSA.

This machine, is a one-of-a-kind observatory built to unveil how the universe first began to shine and much, much more. It’s the largest and most ambitious space telescope ever made and promises to produce one of the most incredible discoveries of our lifetime and beyond, and I’m very excited to see how it will end.
