Galaxies may have any of four general shapes. Elliptical galaxies show little or no structure and vary in general shape from moderately flat and round or oval to spherical. Spiral galaxies have a small, bright central region, or nucleus, and arms that come out of the nucleus and wind around, trailing off like a giant pinwheel. In barred spiral galaxies, the arms extend sideways in a short straight line before turning off into the spiral shape. Both kinds of spiral systems are flat. Irregular galaxies are usually rather small and do not have a symmetrical shape.

What are galaxies classified as?
they are classified by there shape .
What are three types of galaxys?
The three different types of galaxies are the Spiral galaxy, the Elliptical galaxy, and the Irregular galaxy. Spiral galaxies are obviously in the shape of a spiral, elliptical galaxies are shaped as an ellipse, or a flat circle, and irregular galaxies can be any shape.
Galaxies are classed according to their?
historically, galaxies have been classed or categorized according to their apparent shape (usually referred to as their visual morphology).
Along with shape and size which property distinguishes spiral galaxies elliptical galaxies and irregular galaxies from one another?
You can also distinguish them by the types of stars - older stars versus younger stars, and stars of different "metallicity".
Are elliptical galaxies egg-shaped galaxies without spiral arms of interstellar gas and dust?
Yes, that is correct. Elliptical galaxies are characterized by their elliptical or egg-shaped appearance and lack spiral arms of interstellar gas and dust. Unlike spiral galaxies, which have a flattened disk shape with spiral arms, elliptical galaxies have a more rounded or elongated shape. They are composed mainly of older stars and contain little to no ongoing star formation. Elliptical galaxies also tend to have less interstellar gas and dust compared to spiral galaxies.
Why aren't all the galaxy's the same?
No. Galaxies vary greatly in size, mass, shape, and number of stars.
Are all 100000000000 galaxies in our universe be any size and shape?
Yes, galaxies can be any size and shape.
Galaxies are classified by their shape what are they called?
There are three types of galaxies, all of which are the same, with the exception of their shapes. There are the Elliptical galaxies (football-shaped) the Spiral galaxies (like the Milky way; vortex-shaped) and Irregular galaxies (all shapes other than spiral and football shaped).
Are irregular galaxies shapeless?
Yes, irregular galaxies are all shapeless. None of them have a distinct shape.
Do galaxies all look the same?
No.
What are the shape of galaxies?
oval
What shapes do irregular galaxies have?
Irregular galaxies have no discernible shape.
Irregular galaxies are different from elliptical and spiral galaxies because?
Because irregular galaxies have no definite shape.
Are peculiar galaxies strange in shape?
Yes, peculiar galaxies are strangely shaped.
What is the common shape of galaxies?
fartlike

The majority of galaxies are which shape?
