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. 2025 June 17 [2]A starfield is covered with a light red glow. Several nebulas are seen near the center. The famous Rosette nebula appears in blue and white near the image bottom. Please see the explanation for more detailed information. Rosette Nebula Deep Field Image Credit: [3]Toni Fabiani Méndez Explanation: Can you find the Rosette Nebula? The red flowery-looking nebula just above the image center may seem a good choice, but that's not it. The famous [4]Rosette Nebula is really located on the lower right, here [5]colored blue and white, and connected to the [6]other nebulas by gold-colored filaments. Because the [7]featured image of Rosette's field is so [8]wide, and because of its deep [9]red exposure, it seems to contain other flowers. Designated [10]NGC 2237, the center of the Rosette Nebula is populated by the bright blue stars of open cluster [11]NGC 2244, whose winds and [12]energetic light are evacuating the nebula's center. The [13]Rosette Nebula is about 5,000 light years distant and, just by itself, [14]spans about three times the diameter of a [15]full moon. This flowery field can be found toward the [16]constellation of the [17]Unicorn ([18]Monoceros).
