<ul><li>The James Webb Space Telescope has revealed a small early galaxy, nicknamed Firefly Sparkle, that is similar to what the Milky Way may have appeared billions of years ago.</li><li>The light from Firefly Sparkle, which is behind a large cluster of galaxies, is gravitationally lensed, making it bright enough for Webb to see.</li><li>The distortion caused by gravitational lensing gives an exploded view of the galaxy, showing clumps of active star-forming regions and stages of star formation.</li><li>The overall mass of Firefly Sparkle is very similar to the hypothetical mass of the Milky Way at that age, and it also has companion dwarf galaxies.</li></ul>
