You've heard the stories, some of you have been with us since day one, but you’ve never seen the telescope from this side. We recorded every minute of Webb’s journey - the triumphs, the challenges, and the moments that made us question if this was possible. Now, we’ve sorted through hundreds of hours of footage to bring those stories to you, the people who love this telescope as much as we do.
Cosmic Dawn takes you behind the scenes, from developing the idea of a super powerful infrared telescope to watching with bated breath as it unfolded, hurtling a million miles away from Earth.

![“Firefly Sparkle” Reveals Early Galaxy
Dr. Jonathan Gardner presents the latest JWST images of the “Firefly Sparkle” galaxy, showcasing intricate details and structures.
There is so much going on inside this seemingly tiny galaxy, it appears like a swarm of lightning bugs on a warm summer night, this galaxy is gleaming with star clusters.
This is the very first time NASA’s James Webb Space Telescope has detected and examined a galaxy that existed around 600 million years after the big bang, that carries many resemblances to our own Milky Way at a similar stage of its own development.
