The Ring Nebula is about one light-year across and 2,500 light-years away. Publishes the results of original research in astronomy and astrophysics, both observational and. Intense ultraviolet light from the hot central star ionizes atoms in the gas. An official journal of the Royal Astronomical Society. The shape is perhaps fitting for Valentines Day. 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. The Heart Nebula, officially dubbed IC 1805 and visible in the featured image on the upper right, has a shape reminiscent of a classical heart symbol. Today, NASA has shared a breathtaking image of the famous Ring Nebula (M57) captured by the Hubble Space Telescope. Although it would be a major discovery if the rock was truly a fossilized ancient Martian flower. NASA Official: Phillip Newman Specific rights apply. Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU) dedicated to astronomical images. Pictured, the blue supermoon of 2023 was imaged hovering far behind a historic castle and lighthouse in Syracuse, Sicily, Italy.

Smaller than a penny, the rock has several appendages that make it look, to some, like a flower. A modern definition of supermoon is a moon that reaches its full phase when it is relatively close to Earth - and so appears a bit larger and brighter than average. 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. Explanation: It is one of the more unusual rocks yet found on Mars. 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.
