The most widely recognized system for categorizing the general shapes that galaxies form is credited to Edwin Hubble. Although each galaxy has a unique shape, he found they could be categorized into several shapes with common features. There were the rather featureless ellipticals, and then the spiral galaxies including spirals with bars (central bar-shaped concentrations of stars like our own Milky Way); and the lenticulars which have a flat disk shape with a central bulge but no spiral arms, and also irregulars, with odd or more random shapes that fell outside these common ones. Other shape (morphology) classification systems refined or extended these basic shapes, the classification varying because of a different placement of emphasis upon specific features such as star types or densities, presence of rings, and so forth.
What else can I help you with?
Edwin Hubble categorized galaxies according to their?
Shape, or morph. The spiral galaxies, elliptical galaxies, lenticular, barred spiral, and irregular galaxies all are different shapes or morphs of galaxies, and so they are classified differently.
What galaxies are massive blobs of stars?
Elliptical galaxies are massive blobs of stars characterized by their round or ellipsoidal shapes. These galaxies are composed mainly of older stars and have little to no ongoing star formation activity.
Does every galaxy has a solar system?
Not every galaxy has a solar system. Solar systems are specific to individual galaxies, such as our Milky Way galaxy, where planets orbit around a star like our Sun. There are galaxies that may not have stars that form solar systems due to different conditions present in those galaxies.
What galaxies are nebulas found?
Nebulas are found in all types of galaxies, including spiral galaxies like the Milky Way, elliptical galaxies, and irregular galaxies. They are regions of dense dust and gas where new stars are formed. The variety of shapes and sizes of nebulas contribute to the diversity of galaxies in the universe.
Galaxy types from largest to smallest type?
It doesn't really work that way. The types aren't exactly related to size, but rather to shapes. Dwarf galaxies of course are the smallest; but other than that, a spiral galaxy can come in different sizes; so can an irregular galaxy or an elliptical galaxy.
What holds stars together to form shapes of galaxies?
GRAVITY!
Are all galaxies the same size?
All galaxies are different sizes and mainly four different shapes,spiral,barred spiral,elliptical and irregular
Are all of the galaxies in the universe the same?
No. They come in different sizes and different shapes, and have other differences as well.
Different kinds of galaxes?
There are three main types of galaxies: spiral galaxies (like the Milky Way), elliptical galaxies (oval or spherical in shape), and irregular galaxies (lacking a distinct shape). These classifications are based on the galaxies' shapes and structures.
What shapes do irregular galaxies have?
Irregular galaxies have no discernible shape.
What shapes of galaxies do contain H II regions?
Spiral and irregular galaxies.
What cosmic accident is believed to form many irregularly shaped galaxies?
Collisions or interactions between galaxies are believed to be the cosmic accidents that can lead to the formation of many irregularly shaped galaxies. These interactions can trigger bursts of star formation and distort the shape of galaxies, resulting in the formation of irregular shapes.
Why do the same galaxies can appear to have different shapes to different observers?
The reasons are the same as why a bird's eye view of your house would be different from the front or side elevations.
What does different galaxies look like?
Different galaxies have different shapes and sizes according to how many stars are in each. The best way to actually see them "up close" is by looking at images (some amazing ones are taken by the Hubble telescope).
What are the theories of the galaxies?
The two main theories of galaxy formation are the bottom-up theory, where galaxies form from mergers of smaller structures like dwarf galaxies, and the top-down theory, where galaxies form from the gravitational collapse of large gas clouds. The hierarchical model is a popular framework that combines aspects of both theories to explain the variety of galaxy shapes and sizes observed in the universe.
What are the 4 main galaxy shapes?
There are various ways of categorising galaxies, often based on Edwin Hubble's work on the shapes galaxies. Classifications often give the four main types of galaxies as: Spiral (including barred spiral), Elliptical, Lenticular and Irregular.
What is the possessive form of galaxies?
The possessive form for the plural noun galaxies is galaxies'.Example: Their galaxies' paths do not coordinate.
