Messier 74, a grand design spiral galaxy located 32 million light-years away in the constellation of Pisces, shines at its brightest in this combined optical/mid-infrared image, featuring Webb and Hubble data. The red colors mark dust threaded through the arms of the galaxy, lighter oranges being areas of hotter dust. The young stars throughout the arms and the nuclear core are picked out in blue. Heavier, older stars towards the galaxy’s center are shown in cyan and green, projecting a spooky glow from the core of Messier 74. Bubbles of star formation are also visible in pink across the arms.
