James Webb Telescope Discovers Massive 'Big Wheel' Galaxy in Early Universe

The newly identified disk galaxy challenges existing models of galaxy formation, having grown to an immense size just 2 billion years after the Big Bang.

The Big Wheel galaxy, discovered using the James Webb Space Telescope, is a massive spiral galaxy located over 12 billion light-years away.
Formed just 2 billion years after the Big Bang, it is three times the size of comparable galaxies from the same era.
The galaxy’s rapid growth and preservation of its spiral structure defy traditional models of galaxy evolution, which suggest such features form gradually over time.
The Big Wheel resides in an unusually dense region of space, with galaxy concentrations 10 times higher than typical, likely enabling its accelerated development.
Astronomers estimate the chance of finding such a galaxy in their survey was less than 2%, highlighting its rarity and significance for refining cosmic formation theories.
