         | interesting! the (1999) is a mix of old and new:

         | " _This newly processed image comes from data originally
         | captured by NASA's Hubble Space Telescope in 1999 and 2000. The
         | color assignments in this image have been matched to those used
         | in the new 2024 data, providing a better comparison._ "
         | 
         | the original coloring (of the 1999-2000 image) is in the
         | article, or also at

         | with some other details

         | It's frankly hard to tell much difference when put into the
         | same color scheme. Granted, those minute changes represent
         | MASSIVE shifts in the arrangement of matter throughout the
         | nebula, it just doesn't look that way from this far away.

           | The nebula was created by a supernova that exploded about
           | 1000 years ago, and the images were taken 25 years apart, so
           | it's about 2.5% bigger in the newer photo.
           | 
           | Besides the overall expansion, some of the wispy cloudy
           | features seem to have changed more qualitatively, some of the
           | curves have shifted shapes and positions in ways more complex
           | than simple expansion, due to magnetic effects.

       | This kid built a custom telescope platform and was able to

       | Horsehead Nebula, Crescent Nebula, Soul Nebula, various galaxies,
       | all from Earth.

       | "Snaps" isn't quite the right word for photo exposures that are
       | the order of minutes to hours.

         | well for me =)
