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 14
      [2]A busy star field is shown with several large red nebulae. The
     Rosette Nebula is among them and seen on the lower right, while the
     nebula surrounding the Cone Nebula is larger and visible toward the
    upper left. Please see the explanation for more detailed information.

   Explanation: Can you find the Rosette Nebula? The large, [5]red, and
   flowery-looking nebula on the upper left may seem the obvious choice,
   but that is actually just diffuse [6]hydrogen emission surrounding the
   [7]Cone and Fox Fur Nebulas. The famous [8]Rosette Nebula is really
   located on the lower right and connected to the [9]other nebulas by
   irregular filaments. Because the [10]featured image of Rosetta's field
   is so [11]wide and deep, it seems to contain other flowers. Designated
   [12]NGC 2237, the center of the Rosette nebula is populated by the
   bright blue stars of open cluster [13]NGC 2244, whose winds and
   [14]energetic light are evacuating the nebula's center. The [15]Rosette
   Nebula is about 5,000 light years distant and, just by itself,
   [16]spans about three times the diameter of a [17]full moon. This
   flowery field can be found toward the [18]constellation of the
   [19]Unicorn ([20]Monoceros).
