Charles Messier. The first edition of 1774 covered 45 objects (M1 to M45).The total list published by Messier in 1781 contained 103 objects, but the list was expanded through successive additions by other astronomers, motivated by notes in Messier's and Méchain's texts indicating that at least one of them knew of the additional objects.
Skyglobe is an astronomy program for MS-DOS and Microsoft Windows first developed in the late 1980s and early 1990s and sold as Shareware. [1] It plots the positions of stars, Messier objects, planets, sun and moon.
Messier 7 or M7, also designated NGC 6475 and sometimes known as the Ptolemy Cluster, [4] is an open cluster of stars in the constellation of Scorpius. The cluster is easily detectable with the naked eye , close to the "stinger" of Scorpius.
[1] [4] Entries in the catalogue are designated with a "C" and the catalogue number (1 to 109). Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [5] the Caldwell catalogue is ordered by declination, with C1 being the most northerly and C109 being the most southerly, [1 ...
The Butterfly Cluster (cataloged as Messier 6 or M6, and as NGC 6405) is an open cluster of stars in the southern constellation of Scorpius. Its name derives from the resemblance of its shape to a butterfly. [5] The first astronomer to record the Butterfly Cluster's existence was Giovanni Battista Hodierna in 1654. [6]
Messier 73 (M73, also known as NGC 6994) is an asterism of four stars in the constellation Aquarius which was long thought to be a small open cluster. It lies several arcminutes east of globular cluster M72. According to Gaia EDR3, the stars are 1030 ± 9, 1249 ± 10, 2170 ± 22, and 2290 ± 24 light-years from the Sun, with the second being a ...
Messier 34 (also known as M34, NGC 1039, or the Spiral Cluster) is a large and relatively near open cluster in Perseus. It was probably discovered by Giovanni Batista Hodierna before 1654 [ 4 ] and included by Charles Messier in his catalog of comet -like objects in 1764.
