00:00There is so much going on inside this seemingly tiny galaxy.
00:05Nicknamed the Firefly Sparkle for appearing like a swarm of lightning bugs on a warm summer night,
00:11this galaxy is gleaming with star clusters.
00:14Due to its long warped arc, researchers easily picked out 10 distinct star clusters,
00:20each of which have been examined in great detail.
00:23They appear here in shades of pink, purple, and blue.
00:26The color of each helped scientists to confirm that star formation didn't happen all at once in this galaxy,
00:32but was staggered through time.
00:34Using NASA's James Webb Space Telescope,
00:37this is the very first time researchers have detected and examined a galaxy
00:42that existed around 600 million years after the Big Bang,
00:46which carries many resemblances to our own Milky Way at a similar stage of its own development.
00:52Researchers can't predict how this disorganized galaxy will take shape over billions of years,
00:57but there are two other galaxies hanging out within a tight perimeter
01:01that may influence how it builds mass as it evolves.
01:04Each time one galaxy passes another, gas condenses and cools,
01:09allowing new stars to form in clumps, adding to the galaxy's masses.
01:13Previously, scientists were unsure if it would be possible to resolve a galaxy
01:18that existed so early in the universe into so many distinct components.
01:22But Webb was able to image the galaxy well for two reasons.
01:26The first is the benefit of the cosmos.
01:29A massive foreground galaxy cluster radically enhanced and magnified the distant galaxy's appearance
01:35through a natural effect known as gravitational lensing.
01:38When combined with the telescope's specialization in high-resolution infrared light,
01:44Webb delivered unprecedented new data about the galaxy's contents.
01:48The first is continuous,
01:55the second is twitch-tenths.
