2004年9月2日 · This detailed view of spiral galaxy NGC 2403 shows the location of Supernova 2004dj, numerous star clusters, and several other stars that exploded in previous years. The region was observed with the Hubble Space Telescope's Advanced Camera for …

6 天之前 · In this study, we analyzed measurements of the corotation radius obtained using several methods for three galaxies (NGC 3686, NGC 4321, and NGC 2403) that exhibit different morphologies of spiral structures. We also performed independent measurements to estimate the location of the resonance, which allowed us to determine whether each galaxy ...
