The first All-Star Game was held as part of the 1933 World's Fair at Comiskey Park and was the brainchild of Arch Ward, then sports editor for the Chicago Tribune. [1] Initially intended to be a one-time event, its great success resulted in making the game an annual event, with some years (1959–1962) having two All-Star Games.
This is a list of open clusters located in the Milky Way. An open cluster is an association of up to a few thousand stars that all formed from the same giant molecular cloud . There are over 1,000 known open clusters in the Milky Way galaxy, but the actual total may be up to ten times higher. [ 1 ]
A second game was played for four seasons, from 1959 through 1962. The All-Star Game Most Valuable Player (MVP) Award was introduced in 1962 and the first recipient was Maury Wills of the Los Angeles Dodgers. The 2008 game featured the longest All-Star Game by time: 4 hours 50 minutes, and tied for innings at 15 with the 1967 game.
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae.
The regions with higher density of stars are shown; these correspond with known star clusters (Hyades and Coma Berenices) and moving groups. This is a list of nearby stellar associations and moving groups. A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association ...
Globular cluster masses can be determined by observing the proper motion of nearby stars influenced by the cluster [1] [2] or by estimating the cluster's relaxation time. [ 3 ] Open clusters
Globular cluster: Nearest globular cluster to the Earth. Also the first globular cluster known to have exoplanets (PSR B1620-26b) Messier 12: 74.4 [28] Messier 70: 68 [29] NGC 290: 66 [30] Open cluster: Messier 28: 60 [31] Globular cluster: Messier 18: 52.4 [32] Open cluster: The following notable star clusters are listed for the purpose of ...
Star clusters are important in many areas of astronomy. The reason behind this is that almost all the stars in old clusters were born at roughly the same time. [15] Various properties of all the stars in a cluster are a function only of mass, and so stellar evolution theories rely on observations of open and globular clusters.
