The Ring Nebula is about one light-year across and 2,500 light-years away. Intense ultraviolet light from the hot central star ionizes atoms in the gas. Todays Amateur Astronomy Photo of the Day: Archives. Explanation: What is this person doing In 2012, an annular eclipse of the Sun was visible over a narrow path that crossed the northern Pacific. 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. 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. This image of the galaxy was captured by the NASA/ESA Hubble Space Telescope. ![]() Today, NASA has shared a breathtaking image of the famous Ring Nebula (M57) captured by the Hubble Space Telescope. Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU) dedicated to astronomical images. The NGC 2336 galaxy, pictured here, is approximately 100 million light-years away from Earth. ![]() 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. 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.
