they get their colors by the different stars in the galaxy
Elliptical Galaxies.
Elliptical galaxies tend to be reddish in color because they are made up of older stars that emit more red light. These galaxies have used up most of their gas and dust, resulting in a lack of ongoing star formation. This makes their overall color appear reddish compared to younger, bluer galaxies.
Elliptical Galaxies.
Galaxies can have a wide range of colors depending on the stars they contain and how those stars emit light. Generally, galaxies appear in colors like white, blue, red, and yellow. These colors relate to the age and types of stars present in the galaxy.
The milky way is different then other galaxies because it has a milky color and twists in the middle and other galaxies dont have a planet with live humans.Maybe Aliens.Prove me wrong if you want because it might be wrong.Thank you.
Galaxies do not have atmospheres like planets or moons. Galaxies are vast collections of stars, gas, dust, and dark matter bound together by gravity, but lack the distinct atmospheric layers found in celestial bodies like Earth.
Galaxies vary in color and usually are multiple colors. This is due to each galaxy evolving and changing colors as they mature and die.
Astronomers could make this complex mosaic on the side of a large building, but it is unlikely that they would be able to include all 100 billion galaxies (i.e. 60 billion spiral/barred spiral galaxies, 20 billion lenticular galaxies, 15 billion elliptical galaxies, and 5 billion irregular/peculiar galaxies).
No. You can figure out exactly what elements are in stars and galaxies by examining the color spectrum of the light detected; the frequencies of the bright and dark lines in the spectrum tell you what's what. But there's a problem. For distant galaxies, the light spectrum is wrong. The frequency lines of the spectrum are all too low. One possible explanation of the incorrect spectrum is that those stars and galaxies are MOVING AWAY from us, and that the spectrum is shifted toward the red end of the color spectrum because of the Doppler effect. So scientists believe that the "red-shift" on the color spectrum of stars and galaxies indicate that they are moving away. Not all galaxies show a red-shift; the Andromeda Galaxy, M31, shows a pronounced BLUE-shift, indicating that it is heading TOWARD us. In fact, scientists believe that the Milky Way and Andromeda will probably collide in about 3 billion years.
Elliptical galaxies have a red color because the stars in them are older and cooler. An example of an elliptical galaxy is Maffei 1.
Some can be, not all. Galaxies with a lot red giant stars will look red. Red giant:A huge red aging bloated star about 100 times the size of the sun.
