Ring galaxies and lenticular galaxies are ones that have a circle-like appearance (both are subsets of spiral galaxies). Get started today before this once in a lifetime opportunity expires. Typically, the new stars form at the arms of the disk, however, when this type of galaxy does not have arms it is referred to as lenticular, or S0. The bulge is housed at the center of the galaxy. This type of galaxy often contains older, redder stars and can be huge in size when compared to spiral galaxies. Photo by Trevor Jones. Spiral galaxies are classified into two groups, ordinary Spiral galaxies, Elliptical galaxies, and Irregular galaxies. Each irregular galaxy does not have a size or shape that is what we know as regular or normal. It is published, The basic neutral color palette comprises black, white. And some galaxies are interacting with each other and appear to be colliding. This black hole may be part of the reason why new stars do not form often in elliptical galaxies. These 4 galaxies serve as the governing areas for the gods, and so each one is overseen by the According to NASA, the uniqueness of irregular galaxies may be because of interactions they could have had in the past with other, neighboring galaxies. The 3 most common types of galaxies are classified by their shape, and they include spiral, elliptical, and irregular galaxies.

Virgo in particular has over 1,300 galaxies within its borders, and some scientists estimate there could be as many as 2,000 galaxies. Because of their close proximity to Earth, both of these galaxies are pieces of two different constellations. Millions or even billions of years may pass before galaxies merge completely into a single larger galaxy. When galaxies get close, gravity pulls them together, causing a collision. Explanation: The galaxies that have been undisturbed for billions of years are likely to form spiral, disk shaped galaxies. But even if you do not have a telescope, you can still appreciate the beauty of galaxies and admire their various shapes and sizes.

NGC 1300 is a part of the constellation Eridanus and NGC 1365 is a part of Fornax. Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth. Certain constellations, such as Virgo, contain galaxy clusters. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre. For both spiral and barred spiral galaxies, after the initial notation of the broad classification, there is a more specific classification noting the tightness of the spiral. Spiral galaxies have a 'twisting swirl' shape and often have younger, bluer stars. Here is a list of the brightest galaxies you can observe with the naked-eye under clear, moonless conditions.
