NASA Webb Uncovers Unusual Galaxy Shaped by Cosmic Collision

July 06, 2026

$A horizontal image of the galaxy Centaurus A stretches across a black background filled with thousands of tiny purple, pink, and white points of light. The galaxy is brightest at its center, where a brilliant white and pale pink glow radiates outward. Eight diffraction spikes extend from the central glow. Delicate loops and wispy ribbons of pink and lavender arc above and below the center of the image in the shape of an ‘S’. A band of gray and white dust in the shape of a parallelogram cuts across the middle of the galaxy. Mottled patches and bright knots are scattered throughout the dusty band. The galaxy’s outer edges fade into soft, cloud-like plumes with feathery textures that stretch toward the left and right sides of the image. Against the surrounding darkness, a few bright foreground stars shine with Webb’s distinctive diffraction spikes, while countless fainter stars create a speckled backdrop.$

$FS Tau, a star-forming nebula. Clouds of transparent blue and purple gas and dust stretch from the center to the right. Several yellow and white protostars, some showing Webb’s eight-pronged diffraction pattern, are dispersed throughout the clouds. Orange wisps and filaments of gas extend from one of the protostars at the center toward the top left and bottom right corners. There are numerous, distant yellow and white galaxies strewn about the black background of space.$
