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. [1] Members of stellar associations and moving groups share similar kinematic properties, as well as similar ages and chemical composition. The list (below) is sorted by the distance to the Solar System.
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 ]
An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. Astronomical catalogs are usually the result of an astronomical survey of some kind.
This is a partial list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities ...
In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
OANTON was dedicated in February 1942 in a ceremony attended by the President of Mexico, Manuel Ávila Camacho, and other dignitaries. [2] The project was begun some time earlier by Luis Enrique Erro , who was an astronomer by training but for many years had been the Mexican ambassador to the United States.

It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.
