The Triangulum Galaxy - M Poster
Vægplakat af billedskaberen Michael Kalika, der beskriver værket; The Triangulum Galaxy (also M 33, NGC 598) is a spiral galaxy in the constellation Triangulum. The third-largest galaxy of the local group after the Andromeda Galaxy and the Milky Way, is 5-10 times less than the Milky Way in mass. The diameter is 2 times smaller than the Milky Way and 4 times smaller than the Andromeda galaxy. Its diameter - about 50 thousand light-years correspond to the average value typical for spiral galaxies. The galaxy is located at a distance of 2.770-3.070 million light-years from us. In one of its spiral arms is the emission nebula (a small pink cloud to the right of the center) NGC 604, 1300 light-years across - the largest isolated region of star formation, where more than 200 hypergiant stars are concentrated. In 2007, astronomers using the Hawaiian Gemini telescope and the Chandra X-ray telescope discovered a black hole candidate M33 X-7 in this galaxy. Its mass is approximately 16 times the mass of the Sun. It is one of the largest known stellar-mass black holes. But such objects, of course, are inferior in scale to supermassive black holes located in the centers of galaxies. Imaged by me on September 3rd, 2021, from the desert.
