   Explanation: A mere 56 million light-years distant toward the southern
   constellation Fornax, NGC 1365 is an enormous barred spiral galaxy
   about 200,000 light-years in diameter. That's twice the size of our own
   barred spiral Milky Way. This sharp image from the James Webb Space
   Telescope's Mid-Infrared Instrument (MIRI) reveals stunning details of
   this magnificent spiral in infrared light. Webb's field of view
   stretches about 60,000 light-years across NGC 1365, exploring the
   galaxy's core and bright newborn star clusters. The intricate network
   of dusty filaments and bubbles is created by young stars along spiral
   arms winding from the galaxy's central bar. Astronomers suspect the
   gravitational field of NGC 1365's bar plays a crucial role in the
   galaxy's evolution, funneling gas and dust into a star-forming
   maelstrom and ultimately feeding material into the active galaxy's
   central, supermassive black hole.
