What makes a star glow??

I need to know asap!!! What makes a star glow different colors??? Please just help me find some info about this!!! Help please!!! Thanks

Hi! The other s above are sincerely over answering your question. Earth's own atmosphere makes the colors glow differently, due to the the makeup of your atmosphere, and how it tends to change and reflect light differently. If you should be using, say the Hubble Telescope, colors may then tend to change somewhat because of the constant changes happening within any particular star. You've got nuclear explsoions going off, chemicals changing, gases being created and changed, so much is going on out there. Oh, as an example of our atmosphere changing light and colors, just look at how many different colors of the sun that we see through as time passes. Good luck! Don

the reflection of the moon hits the stars so it seems like its changing colors when its not just like how the sky is blue because the sun hits the oceans and it glares off the water and it makes it blue ,so when the moons reflection hits the starts it looks like it changes colors

Uhhh no... it has NOTHING to do with the moon... ù___ú

The color of the stars depends on their relative temperature, and/or the amount of energy they released.

As the energy level of radiation is increased, the wavelength becomes shorter and shorter. When the human eye perceives different wavelengths of visible light, we interpret it as different colors. This is why a rainbow always appears with the same colors in the same order. Red, orange, yellow, green, blue, indigo, and violet. You will never see a rainbow with any other colors, or with the colors in any other order.

The coolest stars are around 3,000 degrees c. They are the red stars. Stars like the sun are next, glowing at about 6,000 degrees c., and are, of course, orange/yellow (although our Sun is actually greener than you think).

10,000 degrees will be a green star, and a blue star is around 25,000 degrees c. There are cool stars which radiate in the infrared, and will last dozens of billions of years. There are stars which expend their energy in the ultraviolet, and will last only a fraction of the lifetime of the Sun. Many of these stars cannot be seen with the naked human eye.

 
When viewed from the earth, the earth's atmosphere has a lot to do with the twinkling and color perception of stars.

Outside of earth's atmosphere, one of the things that determines the redness of a star or Galaxy is the red-shift caused by the speed at which the star or Galaxy is moving away from us.

Stars have different colors because of their temperatures which depends on mass.

In order from coolest to hottest-
Red, Orange, Yellow, Green, Blue

A stars color is composed of the combination of different frequencies of light.

White light is produced by a balanced combination of the colors.

Our sun for example has an absence of blue light, which gives it's yellow bias.

High Guys - I have been observing these objects for about 2 years.
On a clear night I can see 6 of these objects, in the same position relative to
the other night stars.
I live in a very unpolluted place in western Australia.
Most nights I can see a clear view of our Milky Way Galaxy.
It is funny that I read something not long ago, about how our ancestors from
50 years ago, used to be able to see this {The MilkyWay}
I don't know where you live, but these are as clear as day to me.
