Messier 9 or M9 (also designated NGC 6333) is a globular cluster in the constellation of Ophiuchus. It is positioned in the southern part of the constellation to the southwest of Eta Ophiuchi , and lies atop a dark cloud of dust designated Barnard 64.
[9] [10] 2020 — On October 8, 2020, scientists released the largest and most detailed 3D maps of the Universe, called "PS1-STRM". The data of the MAST was created using artificial neural networks and combines data from the Sloan Digital Sky Survey and others. Users can query the dataset online or download it in its entirety of ~300GB.

The Pleiades (/ ˈ p l iː. ə d iː z, ˈ p l eɪ-, ˈ p l aɪ-/), [8] [9] also known as Seven Sisters and Messier 45 (M45), is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus.
The next Europe-focused map was published by cartographer Johannes Putsch from Innsbruck in 1537, at the beginning of the Early Modern Age. [ 4 ] The Putsch-map was the first to depict Europe as an Europa regina , [ 5 ] [ 4 ] [ 6 ] with the European regions forming a female human shape with crown , sceptre and globus cruciger . [ 4 ]
Other astronomers, using side notes in Messier's texts, eventually filled out the list up to 110 objects. [9] The catalogue consists of a diverse range of astronomical objects, from star clusters and nebulae to galaxies. For example, Messier 1 is a supernova remnant, known as the Crab Nebula, and the great spiral Andromeda Galaxy is M31.
A Messier marathon is an attempt, usually organized by amateur astronomers, to find as many Messier objects as possible during one night. The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep-sky objects ( galaxies , nebulae , and star clusters ).
In classical antiquity, Europe was assumed to cover the quarter of the globe north of the Mediterranean, an arrangement that was adhered to in medieval T and O maps. Ptolemy's world map of the 2nd century already had a reasonably precise description of southern and western Europe, but was unaware of particulars of northern and eastern Europe.
