Swan dive into this starfield 🦢    Messier 17, also known as the Omega Nebula or Swan Nebula, is one of the largest star-forming regions in the Milky Way galaxy. In this image by NASAHubble, the central portion of the nebula has been colorized to highlight certain wavelengths of light. Green represents oxygen, while red reveals hydrogen and infrared light.     The Swan Nebula is located 5,500 light-years away from Earth in the constellation Sagittarius and is home to one of our galaxy’s youngest star clusters. The young stars in this cluster are difficult to see because of the gas and dust that surrounds them. The powerful radiation from the young stars evaporates and erodes the dense clouds of cold gas in which new stars form.     Image description: Blue and orange stars glitter across the image, interwoven with dark clouds of brown dust and bright, glowing regions of blue.    Credit: NASA, ESA, and A.
