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).
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.
Why do some scientists think that IrII galaxies have irregular distorted shapes?
They collided with another galaxy
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.
Why do some scientists think that Irr II galaxies have irregular distorted shapes?
because it was made like that
Do galaxies all have the same shape?
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 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.
Do all 100 billion galaxies come in all shapes sizes and colors?
Yes. All 100 billion galaxies come in all shapes, sizes, and colors.
Will astronomers classify all the shapes of the 100 billion galaxies in the universe?
There's an impossible way to classify all the shapes of 100 billion galaxies in the universe.
Will astronomers classify all the shapes of 100 billion galaxies in the observable universe?
Someday astronomers may have classified all the shapes of 100 billion galaxies in the observable universe.
What holds stars together to form shapes of galaxies?
GRAVITY!
