For the first time, astronomers have spotted and "weighed" a baby Milky Way-like galaxy lurking in the early universe, using incredibly detailed images from the James Webb Space Telescope (JWST). The researchers discovered the galaxy, named "Firefly Sparkle" because the dots in it resemble the glowing insects, thanks to a quirky space-time phenomenon predicted by Albert Einstein.
The light coming from Firefly Sparkle dates to around 600 million years after the Big Bang, which occured around 13.8 billion years ago. The young galaxy was spotted thanks to JWST's unmatched power to resolve fine details, coupled with "gravitational lensing."
