JWST finds spiral galaxy about 5 times more massive than Milky Way — scientists call it 'Big Wheel'

Scientists have uncovered a massive galaxy that existed just 2 billion years after the Big Bang. But how did this colossal "Big Wheel" form so early in the universe? The answer could change everything we know about galaxy growth.

A spiral galaxy in the young universe attracts attention because of its size and age. It is nearly as large as our galaxy and about 11.8 billion years old.
