ALT A Webb telescope image of galactic pair IC 1623. The two galaxies appear to be swirling together into a blue and pink ball at the center of the frame. Long, blue spiral arms stretch vertically, faint at the edges. Tendrils of hot gas spread horizontally over the blue arms, mainly bright coral pink with many small gold spots of star formation. The very center of this ball of merging galaxies is extremely bright, radiating eight large, golden diffraction spikes. The background is black, with many tiny galaxies in orange and blue.
