The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and has an H II region .

2024年9月12日 · Famously known as the Lagoon Nebula, Messier 8 shines by the ionizing ultraviolet radiation of its embedded young stars. A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this …

The Lagoon Nebula includes an embedded open star cluster (NGC 6530) with hot stars that power the nebular glow. M8 spans 33 light-years across and glows at a visual magnitude of 6. This makes this nebula an excellent choice for observation through an …

2023年8月10日 · Messier 8 (M8) is the formal designation for this nebula. It’s a large gas cloud within our Milky Way galaxy, barely visible to the human eye under good conditions, but glorious with a dark sky...

2015年2月20日 · Messier 8 (M8), also known as the Lagoon Nebula, is a large, bright emission nebula located in the constellation Sagittarius. The star-forming nebula has an apparent magnitude of 6.0 and lies at a distance of 4,100 light years from Earth. It has the designation NGC 6523 in the New General Catalogue.

Messier 8 or M8 (also designated NGC 6523) is a nebula and star cluster in the constellation Sagittarius. It has an apparent visual magnitude of 6 and its angular diameter is 90x40 arc-minutes. M8 lies at an estimated distance of 5200 light years.

2010年10月15日 · Also known as M8, the nebula is a star-forming region in the constellation Sagittarius. Hubble's remarkably sharp, close-up view reveals undulating shapes sculpted by the energetic light and winds from the region's new born stars. Of course, the Lagoon Nebula is a popular target for earthbound skygazers, too. Image Credit: NASA.

Like the Great Nebula in Orion (M42), M8 is a vast star-forming region in which extremely luminous young stars pump radiation into the surrounding nebula, causing it to glow. Silhouetted against this light we see dark globules of gas and dust, cocooning even younger protostars.

2023年8月4日 · This star chart for M8 represents the view from mid-northern latitudes for the given month and time.

Also known as M8, the bright star forming region is about 5,000 light-years distant. But it still makes for a popular stop on telescopic tours of the constellation Sagittarius, toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this stunning, deep view ...
