Star Clusters Click the icon to view Star Clusters of the Messier Catalog >> Links >> Globular Globular clusters are gravitationally bound concentrations of approximately ten thousand to one million stars. Spectroscopic study of globular clusters shows that they are much lower in heavy element abundance than stars such as the Sun that form in …
Nebulae Click the icon to view Nebulae of the Messier Catalog The icon shows the Horsehead Nebula (Barnard 33), a dark nebula superimposed on an emission nebula (IC 434). Diffuse Nebulae Diffuse nebulae are clouds of interstellar matter, namely thin but widespread agglomerations of gas and dust. If they are large and massive enough they …
Messier Object Data, sorted by Right Ascension The old Charles Messier has expressed his plan to bring out his catalog anew, ordered by right ascension; he published this plan in the Connaissance des Temps for 1801, but he never carried it out. But as this order is convenient and was applied to many other catalogs, …
Messier Object Data, sorted by Declination This ordering scheme was recently introduced by Patrick Moore in his Caldwell Catalog. Certainly, we can present the Messier catalog in the same order. Type: 1=Open Cluster, 2=Globular Cluster, 3=Planetary Nebula, 4=Diffuse Nebula, 5=Spiral Galaxy, 6=Elliptical Galaxy, 7=Irregular Galaxy, 8=Lenticular (S0) Galaxy, 9=Supernova Remnant, A=System of 4 stars or …
Messier Object Data, sorted by Apparent Visual Magnitude Here we present the Messier catalog in the order of decreasing visual magnitude; this should roughly coincide with difficulty. Note, many of the magnitudes are not very well determined, so this order should be taken with the appropriate care. Type: 1=Open Cluster, 2=Globular Cluster, 3=Planetary Nebula, 4=Diffuse …
