| Video Discription | 🌍 What are other galaxies in the universe like? Are they so different from our own? What if we went to explore the galaxies closest to the Milky Way, more specifically those that are part of the Local Group. Galaxies that are far away on our scale, and yet so close to ours, such as the Andromeda galaxy, the Triangulum galaxy or the Great Magellanic Cloud galaxy. But so many other galactic objects, which, although very modest in size, play a fundamental role in our understanding of the Universe. What is the composition of these galaxies? What is their history or even their future evolution? 🔥 As a reminder, the videos are published on SUNDAYS at 6:00 PM. ------------------------- 💥 Journey to the discovery of other galaxies: - The Andromeda Galaxy, with its 1000 billion stars, is often considered the twin sister of our Milky Way. Measuring 220,000 light-years in diameter, Messier 31 is a huge celestial object, the furthest from Earth that can be observed with the naked eye under clear skies, even though it is 2.5 million light-years away. The first observations of this luminous spot go back to the dawn of time, but the first written records date back to 964; they are due to Al-Soufi, a Persian astronomer. The Andromeda galaxy, located in the constellation of the same name, is easily recognized by its oval and diffuse shape with a bright core. The latter, of yellow color, contrasts with the dark dust bands and the large arms that trace their way around. This is a spiral galaxy, the closest to our Galaxy, which offers us a breathtaking spectacle. In its meanders, we can see clusters of blue stars, but also nebulae of reddish color. The total mass of the Andromeda Galaxy, estimated at 1,230 billion solar masses, against 1,900 billion solar masses for the Milky Way, does not prevent it from containing a considerable number of stars more. It houses in its bowels a supermassive black hole estimated at 140 million solar masses, which is much larger than the one in our Galaxy, which is estimated at only 4 million solar masses. Let's start by observing the Large Magellanic Cloud which is a dwarf galaxy of the barred spiral type. It is located in the constellations of the Dorado and the Table. Its disk shape is characterized by the presence of a single spiral arm and a large bar that were discovered long after the galaxy itself, which explains why it was first catalogued as an irregular galaxy. The Large Magellanic Cloud is 163,000 light-years distant from our solar system, but more importantly, it occupies the 4ᵉ position in the Local Group in terms of mass, after the Andromeda Galaxy, the Milky Way, and the Triangulum Galaxy. Several hundred thousand giant and supergiant stars are recorded there, as well as 60 globular clusters, 400 planetary nebulae and 700 open clusters... ------------------------- 🎬 On the program today: - 00:00 - Introduction - 01:50 - The main members of the Local Group - 02:15 - The M31, M32 and M110 Trio - 06:30 - The spheroidal dwarf galaxies of the Andromeda subgroup - 11:00 - The Magellanic Clouds - 12:15 - M31 and M110 to be presented to the public at the end of the year - 18:43 - NGC 185 and NGC 147 - 21:30 - Barnard's Galaxy - NGC 6822 - 22:53 - IC 1613 - 24:46 - Spheroidal Dwarf Galaxies in Milky Way Subgroup - 25:08 - Antlia 2 - 28:02 - Sagittarius Dwarf Galaxy - 30:06 - Dragon Dwarf Galaxy - UGC 10822 - 32:20 - Little Dipper Galaxy - UGC 9749 - 33:39 - Sculptor Dwarf Galaxy - 35:07 - Sextant Dwarf Galaxy - 37:25 - Dwarf Carina Galaxy - PCG 19441 - 38:28 - The Furnace Dwarf Galaxy - 40:14 - The Leo I and II Galaxies - Leo I and Leo II - 41:50 - Ultra-faint spheroidal dwarf galaxies of the Milky Way subgroup - 42:13 - Segue 1 galaxy - 44:28 - Segue 2 Galaxy - 45:58 - The Great Dog Dwarf Galaxy - 47:55 - Dwarf Big Dipper Galaxy I = Ursa Major I - 49:00 - Dwarf galaxy of the Great Bear II - Ursa Major II - Uma II - 51:13 - Dwarf galaxy Reticulum II - 53:22 - Isolated spheroidal dwarf galaxies - 54:10 - Whale dwarf galaxy - 55:43 - Toucan Dwarf Galaxy - 57:04 - KKR 25 galaxy - 57:41 - KKS 3 Galaxy - 58:42 - Bedin I Galaxy - 01:01:45 - Irregular Dwarf Galaxies - 01:02:03 - IC 10 Galaxy - 01:03:59 - Leo III Galaxy - Leo A - 01:05:39 - Periphery near the Local Group - 01:06:05 - Galaxy NGC 55 - Caldwell 72 - 01:08:03 - Galaxy NGC 300 - Caldwell 70 Wondody is an official channel affiliated to the network ©Production Orbinea |
