Hotter stars flow with light that is more intense at shorter wave lengths. The hottest stars emit their radiation in short violet light wavelengths. Their light appears blue white when observed.

Do stars and planets glow?
Stars do, by their own power. Planets merely reflect light.
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
Does a star get brighter when is hot or cold?
Any hot object will glow brighter when it is hotter.
Does a planet glow?
No. planets do not glow, they reflect light, like the moon does. The moon does not glow by itself. the light from the sun hits it and reflects and that light is the light we see comign from the moon. The other planets also do this likewise.
Why are stars visable at night?
Technically the stars are always visible 24 hours a day every day of the week. Stars shine and always continue to shine until they die in a supernova. The stars are not visible during the day because the light of the sun outshines all the light provided by the stars. However, during the night, when the sun is on the other side of the Earth, there is not enough external light to outshine the light of the stars. As a result, the stars are easily visible. However, there are instances that can prevent one from seeing stars even at night. For example, the bright lights of New York City cast a huge glow on the horizon, preventing anyone from seeing the stars past a "light barrier" created on the horizon.
What causes star to glow?
Stars glow because they are hotter than the surrounding area. See related question.
Do nebulas glow?
No, they reflect the light from surrounding stars.
Do stars and planets glow?
Stars do, by their own power. Planets merely reflect light.
Why do stars light up the sky?
Stars generate light by nuclear fusion. That happens in their cores, but the outer layers glow with it.
What is the difference between red hot and white hot?
When some objects get hot enough, they glow, given off a faint red light . If they get even hotter, the glow turns into white light. The objects are said to be white light
What helps the stars glow?
The fusion occurring in the stars cause large amount of light, heat, and radiation causing the stars luminosity.
What color will an interstellar gas cloud composed of hydrogen glow?
It all depends on how close stars are to the cloud, and how intense those stars radiate energy. A nebula will glow with a blue colour if it simply reflects starlight (the blue is from the same mechanism our sky is blue, from the scattering of light). This occurs when a nebula is too far from stars, or the stars are too cool to generate enough radiation to ionize the hydrogen. Nebula will glow red if they are close enough to stars to absorb energy - that energy is re-emitted by the nebula as red (from the ionization of the hydrogen, which then glows red).
Are big stars cold?
No. All stars are hot. For stars on the main sequence, the largest it is, the hotter it is. When a star leaves the main sequence to become a giant or supergiant it will cool down, but will remain hot enough to glow brightly.
Why do glow-in-the-dark things stop glowing after some time?
When things that are supposed to glow in the dark don't, it is usually because they were not exposed to other sources of light. For example, glow stars only glow if the light in the room they decorate has been on for sometime, in a kind of absorbtion process. Without previous contact with a light source they can't glow.
Why are stars spotted clearly in the areas where the cities are not lit up?
This is due to light pollution. The glow of the city lights can conceal stars.
When was Glow Stars created?
Glow Stars was created on 1993-05-17.
What is the difference between stars and animals that produce light?
Stars produce light by "burning" hydrogen in a nuclear fusion, whereas some animals produce light when chemical compounds mix together to produce a glow
