Leo Triplet (M65, M66, NGC 3628) in my favorite orientation. The galaxies form part of the M66 Group. The three galaxies show signs of gravitational interaction in the past. M66 has drawn out spiral arms that show a high rate of star formation. NGC 3628 has a long tidal tail stream visible in deep exposure image, in addition to it's warped disk in our edge on view.
Messier 81 is a spiral galaxy about half the size of the Milky Galaxy with a diameter of 90,000 light years, lies about 12 million light years away.
Messier 82 has a diameter of 37,000 light years and is classified as a star burst galaxy. It is undergoing rapid star formation most likely caused by gravitational interaction with M81 and NGC 3077.
NGC 3077 is an elliptical galaxy that appears to have been disrupted by M81 and M82. All of these galaxies belong to the Messier 81 galaxy group. One of the closer galaxy groups to our own Local group.
NGC 4565 or the Needle Galaxy, edge on view of a spiral galaxy located in Coma Berenices, around 40 million light years away. A prominent dust lane is visible the entire length of the galaxy. Slightly larger than our own galaxy, with over two hundred globular clusters that surround the galaxy.
M 33 or the Triangulum Galaxy at only 3 million light years away, is the third biggest galaxy in our local group of galaxies. It is a smaller spiral galaxy with a size of 60,000 light years across compared to M 31's 220,000 light years size. Furthest distance object that is capable of being seen with only the eye, although it would take clear and dark skies to see it. Probably first recorded by Giovanni Battista Hodierna in 1654. Compiled by Charles Messier in his catalog in 1771.
Start off the year with a galaxy, NGC 772. 130 million light years away in Aries, at twice the size of our galaxy. Elongated spiral arm probably caused by one of its satellite galaxies.
Located in Sculptor, of course, the Sculptor Galaxy is sometimes referred to as the Silver Dollar Galaxy. It is one of the brighter galaxies after the ones in the Local Group.
Discovered by Caroline Herschel in 1783, William Herschel added it to his catalog of deep sky objects.
Imaged with a remote telescope located in Australia.
Messier 77 is an active galaxy located in the constellation of Cetus (The Sea Monster). It has an active galactic nucleus and is classified as a type 2 Seyfert galaxy. It is one of the closest of this type of galaxy.
The first supernova detected in this galaxy was discovered on November 24, 2018 by the DLT40 Survey and was given the name of SN2018ivc. It is classified as a type II supernova which is a core collapse of a massive star.
NGC 891 is an edge on spiral galaxy in which the disk of the galaxy shows many dusty regions. Filaments of the dust extend out from the disk, it is thought that supernova explosions might have caused them.
NGC 6503 Nicknamed the Lost in Space Galaxy as it sits on the edge of an area of space devoid of galaxies that is called the Local Void. A dwarf galaxy at one third of the size of the Milky Way it located in Draco at a distance of 17 million light years away. Also tracked down two quasars that are visible in the image.
Imaged with the ES127 refractor and Atik314l+ mono camera over multiple nights.
Messier 31, or more commonly known as the Andromeda Galaxy, is one of the largest members of our local group of galaxies. Charles Messier added it to his catalog in 1764.
Until 1917 it was thought it was just a nebula located in our galaxy until Heber Curtis observed several nova in M31 and recorded they were about 10 magnitudes dimmer than the local ones in our galaxy. He proposed that M31 was a separate galaxy apart from ours. His theory wasn't proven until 1923 when Hubble measuring Cephid variables visible in M31 and measured its distance at 750,000 light years. In 1943 Walter Baade doubled the distance by measuring the different types of stars in the central region of the galaxy, and discovering two types of Cephid variable stars in the galaxy.
The galaxy is thought to have been shaped by the merger small galaxies 10 billion years in the past, and it appears the Andromeda galaxy and the Milky Way galaxy may merge in around 4 billion years.
