Giant Milky Way-like galaxy formed unusually soon after the big bang

The Big Wheel, discovered using the James Webb Space Telescope, formed just 2 billion years after the big bang - surprisingly early for a spiral galaxy of a similar size to our Milky Way

NASA Webb Wows With Incredible Detail in Actively Forming Star System At the center is a thin vertical cloud known as Lynds 483 that is shaped like an hourglass with irregular edges. At lower center are two discrete bright white, tiny blobs of light that have raced away from the hidden central stars. The top lobe shows a more prominent orange U-shape. Orange bleeds into light purple, and brighter pink at its edges. Some background stars are visible through sections of this lobe. Higher up, there is an orange arc. Some brighter pink material extends to the top edges near the center. In the lower lobe, less orange is visible. More opaque light purple is in its top third, rippling out into semi-transparent blues and pinks. The lower lobe has more texture. V-shapes left and right of the lobes are darkest, and the background stars in these areas appear orange. Elsewhere, the black background of space is clearer, speckled with tiny white stars and faint orange galaxies. Shimmering ejections emitted by two actively forming stars make up Lynds 483 (L483). High-resolution near-infrared light captured by NASA?s James Webb Space Telescope shows incredible new detail and structure within these lobes. Credits: NASA, ESA, CSA, STScI
