Scientists studying the early Universe have uncovered an intriguing mystery surrounding a galaxy observed just 330 million years after the Big Bang.
The galaxy, known as JADES-GS-z13-1, is showing bright hydrogen emissions that should have been absorbed by the cosmic fog, suggesting that the fog may have cleared earlier than previously thought.
The discovery was made using the James Webb Space Telescope (JWST), which detected intense Lyman-alpha hydrogen emission from the ancient galaxy.
The findings challenge current theories about the transmission of light and galaxy formation in the early Universe, and further studies are needed to unravel the mystery.
