Galaxies that have a bright center that contains very little dust and gas?

Stars come in a variety of types. Blue stars, which are very hot, tend to have shorter lifetimes than red stars, which are cooler. Regions of galaxies where stars are currently forming are therefore bluer than regions where there has been no recent star formation. Spiral galaxies seem to have a lot of gas and dust, while elliptical galaxies have very little gas or dust.

What are galaxies that have very bright centers and very little dust or gas called?
elliptical
Do spiral galaxies have very bright centers and little gas and dust?
No. They have a spiral shape.,
What type of galaxy includes little gas and dust and no longer produces stars?
the galaxy that contains no blue stars is I DO NOT KNOW and i would like to know the answer too
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.
Compare and contrast the three types of galaxies?
Galaxies that appear to have a bulge in the middle and arms that spherical outward, like pinwheels, are spherical. Elliptical galaxies look like round or flattened balls. Galaxies that do not have regular shapes are known as irregular galaxies.
What was the name of Little Bear's wife from Indian in the cupboard?
Little Bear's wife in "The Indian in the Cupboard" was named Bright Stars.
Why cant you see black holes from earth?
Black holes emit so very little radiation they are hard to see. Many black holes lie at the center of galaxies and there they are hidden by stars and dust.
What is a bright distant galaxy with a black hole in it?
Perhaps you are referring to quasars. Quasars are (galaxies with) extremely active galactic nuclei.Otherwise, as far as we know, many of the larger galaxies seem to contain a supermassive black hole in the center. If by black hole you are referring to standard black hole, not a supermassive, chances are all galaxies have quite a few. Within the local group of galaxies (Our cluster), the brightest galaxy as it appears from Earth is the Canis Major dwarf galaxy at 25,000 lightyears away. For galaxies not within our cluster, the brightest would be Markarian 231 at about 600,000,000 lightyears away.Comparing apparent magnitude. Canis Major's apparent magnitude (Little "m") is approximately 23.3m where Markarian 231 is about 13.8m yet the galaxy is 2,400,000% further away than Canis Major. An interesting side note about this galaxy is that it's supermassive blackhole is accompanied by a large quasar.
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.
What color combinations make cyan color?
Bright blue + a little bright green
What are all the courses of super Mario galaxy 2?
There is little information on the galaxies as of yet.
Why do galaxies expand primarily on one plane as oppposed to all planes ie a plate instead of a sphere?
Because galaxies don't expand. The universe expands. Think of galaxies as little spots on a balloon. When you blow it up the surface gets larger not the little spots, but the spots do get further apart. Gravity creates the extreme flatness that you observe. Moments after the big bang the initial structure of the universe was set, that applies to the size of the galaxies as well. The only observable difference is the galaxies were a lot closer to each other in the beginning. Gravity then took over and started effecting the closest galaxies by pulling them closer together. The galaxies face a battle between the expanding universe and the gravity of other galaxies.
