   Explanation: [9]Beautiful spiral galaxy Messier 74 (also known as NGC
   628) lies some 32 million light-years away toward the constellation
   Pisces. An island universe of about 100 billion stars with two
   prominent spiral arms, M74 has long been admired by astronomers as a
   [10]perfect example of a grand-design spiral galaxy. M74's central
   region is brought into a stunning, sharp focus in this [11]recently
   processed image using [12]publicly available data from the [13]James
   Webb Space Telescope. The colorized combination of image data sets is
   from two of Webb's instruments [14]NIRcam and [15]MIRI, operating at
   near- and mid-infrared wavelengths. It reveals cooler stars and dusty
   structures in the grand-design spiral galaxy only hinted at in previous
   [16]space-based views.
