HTTP:: The 039 Ring Nebula 039 Captured in Breathtaking Detail
--------
The Ring Nebula is perhaps one of the most “popular†attractions in the sky, having been photographed on numerous occasions with virtually all telescopes capable of resolving it. By combining optical and near-infrared data of the formation, also known under the astronomical designation M57, experts at the Calar Alto Observatory (CAO), in Spain, managed to obtain a new view of it that presented the planetary nebula in a new light. According to AlphaGalileo, this is a unique photograph of the space structure. The image captures not only the central zones of the nebula and its halo, but also a massive number of stars around it, and a huge number of background galaxies, each located at various distances from M57. Experts at the institution say that the photo is part of the Documentary Photo Gallery of Calar Alto Observatory, and that it is the first to be released after the recent image of the Owl Nebula. The two celestial structures are similar in many aspects, but most !
notably in that they are both members of the same class of nebulas. A planetary nebula is formed by stars no larger than eight times the mass of our Sun. They are unable to explode as novas or supernovas, therefore, towards the end of their burning cycles, they emit a lot of their internal matter as stellar winds. After an ad...
