From those characteristics, Galaxy The Milky Way is also known to have a curved shape. A spiral galaxy can be identified as a spinning, flat disk with spiral arms and a bulge in the center. The Milky Way's thickness as we view it from earth is nearly 3,000 light years (just like a CD). The Andromeda galaxy is the closest galaxy to our own galaxy, being around 2.5 million light years away. It is also the largest galaxy of what is called the Local . However, this spiral galaxy is also known by the name: NGC 5457. Galaxies merge to form more substantial and more complex galaxies. NGC 55 is slightly brighter (mag. 5. There is a concentration of the stars in its center, which forms a bulge. The magnificent spiral galaxy NGC 2276 looks a bit lopsided in this Hubble Space Telescope snapshot. A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. 3.

Understanding more about them and how they form and evolve can . Galaxies can range in size from a dwarf with as few as ten million stars to massive giant galaxies with a hundred trillion stars….Galaxy Facts. Fact 3: Our galaxy is 13.2 billion years old. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well. Improving telescope technology enabled astronomers to distinguish the basic shape and structure of . 4: Classified As A Barred Spiral Galaxy. The really bright spots that can be seen . There are four distinct types of galaxies in the universe, elliptical, spiral, barred spiral, and irregular. The arms of the bar-shaped stars extend outwards from the center. Types of Irregular Galaxies : There are mainly three types of Irregular galaxies : 1) Irr- I galaxy 2) Irr- II galaxy 3) dIrr galaxy. As the material falls in toward the black hole, angular momentum will cause it to spiral in and form into a disk. Here is some facts about galaxies!! These galaxies are the most common form of galaxies that have been observed, accounting for 70% of the . 5. Our Milky Way is a spiral, as is the rather close-by Andromeda Galaxy. 2 Twin Galaxies. Barred spiral galaxies also have spiral arms but these arms are connected with a bar of stars. For those who don't know, these are extremely rare occurrences, as only 3% of spiral galaxies have companion galaxies like that. Scientists know that the Milky Way certainly isn't the largest star factory, but it's healthy to say the least. If you look at the spiral galaxy, it has the blue color. The galaxy we live in, the Milky Way, is a spiral galaxy. The cluster has a diameter of 5.8 to 8 million light years and is one of the densest clusters in the sky. Spiral galaxies are disk-shaped with dusty, curving arms. A galaxy is a massive, gravitationally bound system that consists of stars, stellar objects (such as brown dwarfs and neutron stars), nebulae, an interstellar medium of gas and dust, black holes, and an unknown component of dark matter.Examples of galaxies range from dwarfs with as few as ten million stars to giants with a hundred trillion stars or more, each orbiting through their galaxy. They contain stars, dust, asteroids and gas and serve as a residence to a group of stars located in the center of the galaxy. The Milky Way is a bath spiral galaxy: This expands in an area of about 120000 light-years across. 5. The word is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way.Galaxies range in size from dwarfs with just a few hundred million (10 8) stars to giants with one hundred trillion (10 14) stars, each orbiting its galaxy's center of mass. They're called elliptical galaxies. Wow, the universe is huge! While God could have certainly created galaxies in the process of colliding, it's easy to see, given the vast distances between galaxies, how some could interpret this as evidence of great age. In Hubble's scheme, which is based on the optical appearance of galaxy images on photographic plates, galaxies are divided into three general classes: ellipticals, spirals, and irregulars. Least common type of galaxy 6. There are many different examples of galaxies that are spirals, including the Triangulum Galaxy, the Whirlpool Galaxy and the Pinwheel Galaxy.
