M107
Messier 107, also known as the Crucifix Cluster, is a very loose globular cluster in the constellation Ophiuchus. It was discovered by Pierre Méchain in April 1782, and added to the Messier catalogue only in 1947 by Helen Sawyer Hogg together with three other objects found by Méchain. M107 is close to the galactic plane and about 20,900 light-years from Earth
M29
Messier 29, also known as the Cooling Tower Cluster, is a quite small, bright open cluster of stars just south of the central bright star Gamma Cygni in the constellation Cygnus. It was discovered by Charles Messier in 1764. Its age is estimated at 10 million years, as its five hottest stars are all giants of spectral class B0.
M104
Messier 104, also known as the Sombrero Galaxy, is a peculiar galaxy of unclear classification in the constellation Virgo. It was discovered on May 11, 1781 by Pierre Méchain. Charles Messier made a handwritten note about this and five other objects (now collectively recognized as M104 – M109) to his personal list of objects now known as the Messier Catalogue, but it was not "officially" included until 1921.
M6
Messier 6, also known as the Butterfly cluster, is an open cluster of stars in the southern constellation of Scorpius. The first astronomer to record its existence was Giovanni Battista Hodierna in 1654. 120 stars, ranging down to visual magnitude 15.1, have been identified as most likely cluster members. Most of the bright stars in this cluster are hot, blue B-type stars but the brightest member is a K-type orange giant star, BM Scorpii, which contrasts sharply with its blue neighbours in photographs.
M60 | Arp 116
Messier 60, is an elliptical galaxy approximately 57 million light-years away in the constellation of Virgo. Together with NGC 4647, it forms a pair known as Arp 116. NGC 4647 is an intermediate spiral galaxy. The galaxies are located on the outskirts of the Virgo Cluster. On 16 April, the Japanese amateur astrophotographer Kōichi Itagaki discovered a very bright Supernova, also known as SN 2022hrs.
M8 | Sh2-25
Messier 8, the Lagoon Nebula, is a giant interstellar cloud in the constellation Sagittarius. It was discovered by Giovanni Hodierna in 1654 and included in the Messier catalog in 1764. Within the nebula is the open cluster NGC 6530. The Lagoon Nebula is estimated to be between 4,000–6,000 light-years away from the Earth.
M62
Messier 62, also known as the Flickering Globular Cluster, is a globular cluster in the constellation of Ophiuchus. It was discovered in 1771 by Charles Messier. M62 is about 21.5 thousand light years from Earth. The cluster may prove to be the galaxy's richest in terms of RR Lyrae variables. It is hypothesized that this cluster may be host to an intermediate mass black hole.
M11
Messier 11, also known as the Wild Duck Cluster, is one of the richest and most compact open star clusters known, located in the constellation Scutum. The cluster is approximately 6,200 light-years away from Earth and has an estimated age of around 220 million years. It contains thousands of stars, many of which are brighter and younger than our Sun.
M17 | Sh2-45
Messier 17, commonly referred to as the Omega Nebula or Swan Nebula, is an emission nebula in the constellation Sagittarius. Spanning approximately 30 light-years in the longest direction, Messier 17 is located roughly 5,000 to 6,000 light-years from Earth. It is one of the most massive molecular clouds in our Galaxy.
M51 | Arp 85
Messier 51, also known as the Whirlpool Galaxy, is one of the most striking and well-known galaxies in the night sky. What makes it special is the interaction with nearby galaxy NGC 5195, distorting its otherwise symmetric spiral pattern. This gravitational pull has triggered waves of star formation in the Whirlpool's arms, lighting them up with clusters of hot, young, blue stars. Here in a long >60h exposure.
M58
Messier 58 is one of the brightest galaxies in the constellation Virgo. Located roughly 62 million light-years from Earth, M58 is the most distant Messier object. The core contains high rates of star formation, known as starburst activity. It also houses a supermassive black hole around 70 million times the mass of our Sun.
M89
Messier 89 is an elliptical galaxy located in the Virgo Cluster, within the constellation Virgo. M89 is approximately 50 to 55 million light-years away from Earth and has an apparent magnitude of about 9.8 to 10.73. The galaxy contains around 100 billion stars and over 2,000 globular clusters.
