If a galaxy shows any significant colour band, then it is due to the type of stars present in that galaxy. A blue or white galaxy would have to have a predominant amount of OB stars to project that colour band.
Spiral galaxies do not have significantly greater amounts of OB stars, so it is only a "visual" appearance, not a factual one.

∙ 14y agoThe main reason that spiral arms appear blue is that the arms are sites of star formation and are brighter than the surrounding disk.
The stars tend to be young, hot OB stars which are blue (blue-white) in colour.

What colors are spiral galaxies?
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.
How do you use the hard blue and white spiral hair rods?
To use the white and blue spiral hard rods first section your hair off with a comb. Roll each section of hair with a spiral rod and secure with a hair pin.
What do spiral galaxies have a nucleus of?
A spiral galaxy nucleus contains a mass of stars in a "bulge" and is thought that many contain supermassive black holes at the very core of the nucleus.-In galaxies with tightly wound spiral arms the bulge generally contains old, red stars with low metal content (called population II stars); whereas galaxies with more loose arms generally have younger, blue stars (called population I stars). Some bulges have similarities to the elliptical galaxies and others are similar to disk galaxies.-Evidence of supermassive black holes have been discovered in many galaxies and theorized to exist in many more galaxies (at least the larger ones). Our own Milky Way Galaxy contains a supermassive black hole at its core.
What types of stars do elliptical galaxies usually have?
Yes. However, the current rate of star creation is less than when the galaxies were younger.Yes. However, the current rate of star creation is less than when the galaxies were younger.Yes.

What are the colors of the columbine flower?

Why there is a galaxy?
A galaxy is a cluster of stars, nebulae, dark matter, and other astronomical objects. Most galaxies are tens of thousands of light years in diameter, and contain billions of stars. Galaxies come in three primary shapes; spiral galaxies are thin disks, with spiral arms surrounding a central hub; elliptical galaxies are uniform, oval-shaped agglomerations; and irregular galaxies have little or no definite structure. A spiral galaxy centers around a hub, which is roughly spherical and bulges outward from the disk. The hub is the gravitational center of the galaxy, and usually contains a supermassive black hole. Surrounding the hub are spiral arms, which are bunched-up waves of stars and gas orbiting the center. The spiral arms usually have more gas and dust, and they contain most of the newly formed stars, which make them appear blue in color imagery. A spiral galaxy may have a horizontal bar passing through its hub; our own galaxy, the Milky Way, is believed to contain a bar.
How many different colors of stargate chevrons are there and which galaxies do they correspond to?
In our galaxy, they are grey with orange encoders, in the pegasus galaxy, they light up blue with blue encoders, and on the Destiny, they are white with white encoders.
What rivers help the Nile?
Mainly the Blue Nile and the White Nile.

What is the soccer team La Galaxy's colour?
mainly blue and white
What color is microwaves?
my microwave is mainly white and grey with blue and orange
What are the characteristics of the galaxies?
Color. The type of star effects the color. Like temperature wise. Spiral galaxies are generally more blue than elliptical galaxies due to its stars. Size is another characteristic along with luminosity.
