[3] Diameter: 170,000 light-years. All spiral galaxies look like balls with arms. A majority of the observed galaxies fall into this class with around 2/3 of the known galaxies. It has also been speculated that the source of the circular motion of spiral galaxies is the presence of a black hole in its center. This is likely due to the fact that the Milky Way is a spiral; as is the neighboring Andromeda Galaxy. time princess all outfits ; 11:3013:3017:3020:30; apple magsafe portable charger An example of a SBa spiral galaxy is NGC 4314. Sometimes galaxies merge with each which causes them to grow bigger or they are destroyed all together. Stars are actively produced by the Triangulum Galaxy scattered throughout the spiral arms. The Milky Way (like others) changes back and forth from spiral to barred spiral. Usually, spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars. They contain stars, dust, asteroids and gas and serve as a residence to a group of stars located in the center of the galaxy. Spiral galaxies have lots of gas and dust which means it has younger stars. Spiral galaxies provide us with some of the best views in our night sky, and many of the most well known galaxies are actually spirals.

Along with the other types of galaxy, the Spiral galaxy was first defined by Edwin Hubble in 1936. The large stars of a spiral galaxy do not last very long because they are constantly burning large amounts of fuel. A Spiral Galaxy is so called because its flat and arms of the star reach out from the centre outwards. Previously, our galaxy was thought to possess four major arms. Seen from the side, though, it simply looks like a circle. Spiral galaxies are further classified by how tight their arms are e.g. The first galaxies were actually discovered in the 17th Century, although they were not called galaxies until much later by Edwin Hubble. While investigating facts about Spiral Galaxy Between Pegasus And Cassiopeia and Spiral Galaxy Definition, I found out little known, but curios details like: In a vacuum at zero gravity, the turbulence that occurs in plasma copies the spiral galaxy structure of our universe and if you cool it down you get an exact replica of the DNA double helix structure.
