NGC 602 is a young, bright open cluster located in small Cloud of Magellan. Emission and the shock wave from the fixed star push away most of the light gas and dusts forming a nebula known as N 90 and let you wake up the star formation that is new in the edge of nebula. These young previous main sequence stars are still surrounded by a dust, but, by an infrared wavelength, I am observed by Spitzer space telescope [5]. Because this star cluster is located on the part leading to マゼラニックブリッジ of small Cloud of Magellan, it is interested in particular. In other words, the chemical composition is similar to galactic other parts, but a study is easy because I relatively separate [6].

A lot of Milky Way in the distance appears in the Hubble Space Telescope image of NGC 602 by a background, and it is the scene which "is magnificent" [8] "with fascination" [7].
