Galaxies

Galaxy is a system of hundreds of billions of stars. Most galaxies have spiral arms. So does our home galaxy Milky Way. Some galaxies have elliptic or irregular shape.

Below is Andromeda galaxy Messier 31 and its neighbor galaxies M32 and M110. M31 is closest large galaxy to Milky Way and its distance is 2.5 million light years. Picture was taken 6.8.2013 with SkyWatcher 80/600, exposures 6 x 2 minutes, ISO1600.

Another version of M31 image.

M31 image composition and center area with UHC-S filter.

Below are details from M31. On the left NGC 206, group of bright newborn stars. On the middle are globular star clusters in M31.

Galaxy M33 in constellation of Triangulum. M33 has very clear spiral arms. Distance 3 million light years. Picture was taken 15.11.2012 with Celestron 8 F6.3 optics.

Below left: Spiral Galaxy M81 in constellation of Big Dipper. Distance 12 million light years. Picture was taken 24.2.2020 with Helios Skyliner 200/1000 optics. Exposures 14x90s, ISO1600. Below right: Galaxy M82 in constellation of Big Dipper. Distance 12 million light years. This galaxy has something special. It is very bright and it contains a lot of young stars. Exposures 18x90s, ISO1600

Below two images of galaxy M51 in constellation of Big Dipper. Distance 37 million light years. Here the smaller galaxy has done close passing of the larger galaxy. Picture 3.4.2013 has exposures 2 x 6 minutes, ISO1600. UHC-S filter. Picture 2020 was taken with Helios skyliner 200/1000, exposures 8 x 60 seconds, ISO1600. Below right: M106 in constellation of Canes Venatici. Distance 25 million light years. Picture was taken 6.4.2013 with Celestron 8 F6.3 optics. Exposures were 5 x 6 minutes, ISO1600. UHC-S filter.
Galaxy NGC 4565 is called Needle-galaxy. It is in constellation of Coma Berenices. Distance 43 million light years. Picture was taken 27.3.2017 with Celestron 8 F6.3 optics. Exposures 5 x 60 seconds, ISO3200.
Galaxy NGC 4631 is called whale-galaxy. It is in constellation of Canes Venatici. Distance 30 million light years. Picture was taken 27.3.2017 with Celestron 8 F6.3 optics. Exposures 5 x 60 seconds, ISO3200.

Galaxy NGC891 in contellation of Andromeda is seen sideways. Dark dust clouds cover the glow of the stars. Distance 27 million light years. Galaxy M66 in contellation of Leo. Distance 35 million light years. Galaxy NGC 3628 is in constellation of Leo. Distance 35 million light years. Sombrero Galaxy M104 is in Virgo, distance 28 million light years.

Galaxy Messier 87 is a gigantic elliptical galaxy in constellation of Virgo, in the center of Virgo galaxy cluster. Distance 55 million light years. It has a supermassive black hole in its center. In this picture you can see a jet in one a clock direction, coming from the black hole. When stars and matter fall in to black hole they are first going to a rotating disk round the black hole. On the poles of this system jets of matter are rushing into space. In the embedded images you see the jet also by Hubble Space Telescope and the black hole by Event Horizon Telescope. The mass of this gigantic black hole is 6.5 billion times the mas of the Sun. This black hole eats matter the amount of 90 Earths per day. The size is 40 billion kilometers, which is 266 times the distance between the Sun and the Earth. The event horizon, is the boundary where nothing can escape, not even the ligth. Picture taken 2nd of March 2013 with Celestron 8 F6.3 optics. Exposures 5 x 32 seconds and stacked with DSS.
