“Firefly Sparkle” Reveals Early Galaxy - YouTube - NASA Goddard - cosmology

Dr.Johnathan Gardner,Former Deputy Senior Project Scientist for JWST,presents the latest JWST images of the "Firefly Sparkle" galaxy,showcasing intricate details and structures.There is so much going on in this seemingly tiny galaxy,it appears like a swarm of fireflies on a warm summer night.This galaxy is gleaming with star clusters.This is the first time the NASA/ESA/CSA James Webb Space Telescope has detected a galaxy that existed around 600 million years after the Big Bang.This was made possible by a phenomenon known as gravitational lensing that was predicted by Einstein's Theory of General Relativity,in which the gravity of a large celestial object is strong enough to warp spacetime,allowing us to peer at a very distant celestial object.*Credit:NASA Goddard Spaceflight Center in Greenbelt,Maryland.*Cosmology is the study of the origin,evolution and structures of the universe.*Text by NASA Goddard and edited and augmented by Andrew Taylor
