Blue, blue-white, white, yellow, orange, and red. In the visible spectrum. They also emit in non-visible wavelengths. Note that I don't mean it could be any of those colors, I mean it's probably ALL of those colors.

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.
How do you use spiral in a sentence?
Some galaxies are spiral, similar to the Milky Way.
What is the shape of a Spiral Galaxy?
Spiral galaxies are named for the (usually two armed) spiral structures that extend from the centre into the disk.The spiral arms are sites of ongoing star formation and are brighter than the surrounding disk because of the young, hot stars.See related link for a pictorial representation.
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.
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 types or categories for galaxies?
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
How many galaxies are spiral?
Approximately 60% of all galaxies are spiral
How many barred spiral galaxies there?
It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.
How many types of spiral galaxies are there?
Yes. There are two types of spiral galaxies: "S" (normal spiral) and the less common "SB" (barred spiral, with an elongated center).
What are the 3 common galaxies?
galaxie 1, 2, 3, 4 and 5
How are galaxies classifyed?
spiral galaxies (ours), irregular galaxies, and elliptical galaxies.
Are there at least 60 billion spiral galaxies in the universe?
There at least 60 billion spiral galaxies in the universe because the spiral galaxies comprise of about 60 percent of all galaxies which are about 100 billion.
What are 5 different galaxies?
spiral, eliptical, cartwheel, barred spiral, and lenticular galaxies
The local group contains mainly spiral galaxies?
No. It has only 3 big spiral galaxies, but dozens of dwarf galaxies.
How did the spiral galaxies get its name?
because it was spiral
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.
