NASA Astronomy Picture of the Day 2 April 2023: Hubble Telescope captures Ring Nebula
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.
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.
Today, NASA has shared a breathtaking image of the famous Ring Nebula (M57) captured by the Hubble Space Telescope.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.
Intense ultraviolet light from the hot central star ionizes atoms in the gas. The Ring Nebula is about one light-year across and 2,500 light-years away.Located in the Lyra constellation, the Ring Nebula is a planetary nebula that represents the remaining glowing material of a star similar to the sun.
