![]() ![]() The Ring Nebula is about one light-year across and 2,500 light-years away. Download and use 3,000+ Astronomy stock photos for free. Intense ultraviolet light from the hot central star ionizes atoms in the gas. 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. While sharing the photo, NASA explained about the Ring Nebula, "the recent mapping of the expanding nebula's 3-D structure, based in part on this clear Hubble image, indicates that the nebula is a relatively dense, donut-like ring wrapped around the middle of an (American) football-shaped cloud of glowing gas." The gaseous shroud in the image represents the outer layers expelled from the dying, once sun-like star, now a tiny pinprick of light seen at the nebula's center. Today, NASA has shared a breathtaking image of the famous Ring Nebula (M57) captured by the Hubble Space Telescope. Nebulas are often the birthplaces of new stars and planetary systems, as the gravitational attraction between the particles within the nebula causes them to collapse and form into denser regions. Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). More precisely, the tails C/2023 P1 (Nishimura) are growing as it nears the Sun. Discovered only last month, the comet is already near naked eye. More precisely, the tails C/2023 P1 (Nishimura) are growing as it nears the Sun. Stargazers must have noticed an unusual ring-shaped pattern in the sky for so many years and it is called a nebula, which is a cluster of gas and dust in space.
