There are six main types of spiral galaxies, and they are Sa, Sb, Sc, SBa, SBb and SBc. It was discovered in 1781 by Pierre Mechain. Billion of galaxies exist in our Universe, and our Milky Way is just one of them. In fact, they can often be mistaken for stars due to their compact appearance. It may seem to have no discernable structure, but IC 3583 has been found to have a bar of stars running through its center. They consist of a flat, rotating disk containing stars, gas and dust. They have the most variation in size of any type of galaxy, as they can be very large, or extremely small, with some of them being less than 10% of the size of our galaxy, the Milky Way. All galaxies are made up of these same things. The Andromeda Galaxy, also known as Messier 31 or M31, is a spiral galaxy located about 2.5 million light-years (2.410 19 km) from Earth.Located in the Andromeda constellation, it is the closest spiral galaxy to the Milky Way, where our solar system is, although it isn't the closest overall galaxy to the Milky Way..

This is a spheroid packed with lots of stars and contains within it a supermassive black hole that binds together the rest of the galaxy. NASA's Hubble Space Telescope brings the vastness of space into perspective in this mosaic image of the Triangulum galaxy (M33), our neighbor in a collection of dozens of galaxies called the Local Group. The spinning is at hundreds of kilometers per second and this may be what causes the disk to look like a spiral. The Milky Way's shape is that of a spiral; it looks like a disc from the top with spiralling arms winding out from its centre. The Milky Way Galaxy is most significant to humans because it is our sweet home. A spiral galaxy is a kind of galaxy that looks like a flat, slowly rotating disk with a bulge in the centre, and spiral patterns extending outward from the bulge. Galaxies are massive gatherings of space dust, gases, stars, and other celestial objects. The mass of this galaxy is equivalent to 100 trillion stars. 10. The Andromeda galaxy is the furthest object that can be seen with the naked eye. In spite of such a huge number of stars, the distance between Earth and even our nearest star system, Alpha Centauri, is vast. The really bright spots that can be seen . It's a small part of the Milky Way Galaxy. The central bright region at the core of a galaxy is called the "galactic bulge". An Elliptical Galaxy is one of four main types of galaxies that exist in the Universe. M31 is the closest major galaxy to the Milky Way and was often (M99,NGC4254) is a spiral Spiral Galaxy. In the.

An E0 galaxy looks like a circle. Also known . A number of foreground stars in our Milky Way can be seen in the image . Elliptical Galaxies are generally the largest in the universe but spiral galaxies are often teeming with bright new stars - those dusty arms that make up the spiral actually cause new stars and planets to grow. Here are a few types of galaxies: Spiral galaxies look like giant pinwheels. Interesting Facts About Milky Way Galaxy: Introduction Let's take a little journey into the Milky Way to understand . [3] Irregular galaxies appear chaotic, with no definable nucleus or structure. Spiral galaxies are further classified by how tight their arms are e.g. The unprecedentedly detailed portrait of Triangulum is composed of 54 Hubble fields of view stitched together, revealing nearly 25 million . One interesting fact about spiral galaxies is that they have been observed to be rotating in either a clockwise or counterclockwise direction. We know different galaxies and how many stars they have by their shape. The best way to understand the eight main types of elliptical galaxies is simple, an E0 will have a near perfect circular shape, while a E7 will be very stretched out. Spiral Galaxy. 5.
