[00:00:00]Pulsating inside the web telescope's deepest image are tiny red dots that shouldn't exist.

[00:00:06]These are the sparkle clusters, immense groups of millions of stars that formed when the universe was in its infancy.

[00:00:13]For over 10 billion years, these ancient relics have survived the violent collisions and mergers that built our Milky Way. While most early star clusters were ripped apart by gravity or swallowed by growing galaxies, these defiant survivors offer a frozen snapshot of the Big Bang's aftermath.

[00:00:32]Astronomers discovered them by using a massive galaxy cluster as a cosmic magnifying glass, bending light to reveal objects far too faint for any other telescope to see. They are among the oldest known structures in existence, actu as living fossils that prove the universe was already organized and building massive solar systems just 500 million years after time began. We are looking at the literal foundations of the cosmos.
