Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                               2024 February 6
   [2]Spiral galaxy NGC 1566 is shown with an image from Hubble primarily
   in visible light on the upper left, and an image from Webb in primarily
     infrared light on the lower right. A rollover image shows the same
       galaxy with the Webb and Hubble parts reversed. Please see the
                 explanation for more detailed information.

   Explanation: What's different about this galaxy? Very little, which
   makes the [12]Spanish Dancer galaxy, [13]NGC 1566, one of the most
   typical and photogenic [14]spirals on the sky. There is something
   different about [15]this galaxy image, though, because it is a diagonal
   combination of two images: one by the [16]Hubble Space Telescope on the
   upper left, and the other by the [17]James Webb Space Telescope on the
   lower right. The [18]Hubble image was taken in [19]ultraviolet light
   and highlights the locations of [20]bright blue stars and [21]dark dust
   along the galaxy's impressive spiral arms. In contrast, the [22]Webb
   image was taken in [23]infrared light and highlights where the [24]same
   dust emits more light than it absorbed. In the rollover image, the
   other two sides of these images are revealed. Blinking between the two
   images shows which [25]stars are particularly hot because they glow
   brighter in ultraviolet light, and the difference between [26]seemingly
   empty space and infrared-glowing dust.
