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. 2023 February 6 [2]A cluster of stars is seen in the evacuated center of a nebula of gas and dust. Intricate dust pillars occur at both the top and bottom of the image. Please see the explanation for more detailed information. In the Heart of the Rosette Nebula Image Credit & Copyright: [3]Lyman Insley Explanation: In the heart of the [4]Rosette Nebula lies a bright [5]cluster of stars that lights up the nebula. The stars of [6]NGC 2244 formed from the surrounding gas only a few million years ago. The [7]featured image taken in mid-January using multiple exposures and very specific colors of [8]Sulfur (shaded red), [9]Hydrogen (green), and [10]Oxygen (blue), captures the central region in tremendous detail. A hot [11]wind of particles streams away from the cluster [12]stars and contributes to an already [13]complex menagerie of gas and [14]dust filaments while slowly evacuating the cluster center. The [15]Rosette Nebula's center measures about 50 [16]light-years across, lies about 5,200 light-years away, and is visible with binoculars towards the constellation of the Unicorn ([17]Monoceros).
