Firefly Sparkle Galaxy Offers a Taste of Infant Milky Way

Firefly Sparkle: Newly discovered galaxy mirrors Milky Way's early days
For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and "weighed" a galaxy that not only existed about 600 million years after the Big Bang, but also has a mass that is similar to what our Milky Way galaxy's mass might have been at the same stage of development.
Firefly Sparkle galaxy offers a taste of the infant Milky Way
NASA's James Webb Space Telescope has spotted a young galaxy dating to the early universe - called Firefly Sparkle because its gleaming star clusters resemble the bioluminescent bugs - in a discovery that is giving astronomers a peek at what our Milky Way may have looked like in its infancy.
Firefly Sparkle shines a light on a young Milky Way
The young galaxy is only 6,500 light years from its first companion and 42,000 light years from its second. In comparison, the fully formed Milky Way is 100,000 light years across and could easily fit Firefly Sparkle and its companion galaxies inside it.

Why is your discovery of the Firefly Sparkle galaxy important? Telescopes like JWST are essentially time machines. Since light from distant galaxies travels for a long time before it reaches our telescope,
Meet Firefly Sparkle, Webb telescope's galaxy find similar to Milky Way
Firefly Sparkle is a lightweight among the universe's galaxy contenders seen by NASA's James Webb Space Telescope, but the discovery is no less important than more massive galaxies because of what it has in common with our home Milky Way galaxy.
