Commentaires : The Trifid Nebula (also known as Messier 20 and NGC6514) is an H II region with a remarkable collection of open cluster, emission nebula (the lower, red portion), reflection nebula (the upper, blue portion) and dark nebula (the septation within the emission nebula causing the trifid appearance, also designated Barnard 85). www.astronomica.es . ...

... Credit: Anglo-Australian Telescope Board Explanation: The photogenic M 16 shown above is composed of a young star cluster associated with a spectacular emission nebulae lined with clouds of interstellar dust . ... The dust absorbs so much light it allows astronomers to determine which stars are inside the nebula and which are in the foreground. Stars are forming within the nebula, also known as the Eagle Nebula . ... Publications with keywords: star cluster - M16 . ... The Fairy of Eagle Nebula . ...

... Archives . ... Another deduced conclusion from reading preprints listed in arxiv/astro-ph is that astronomers tend to confuse classification and clustering and to mix up methodologies. They tend to think any algorithms from classification or clustering analysis serve their purpose since both analysis algorithms, no matter what, look like a black box . ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...

These clusters are probably young versions of globular clusters, but they are commonly called super star clusters. Seven dwarf galaxies within 16 million light-years have formed super star clusters, with one of these galaxies, NGC 1569, possessing two young clusters. ...
