Red. It's called Redshift
When it moves quickly away it's called Blueshift
the photoshpere emits visible light
false
It's a bulb with more blue light in it, to better match the light that natural sunlight emits.
sun (a luminous object) emits its own light and the moon ( a non luminous object ) reflects the light from the sun to earth that's how we can see the moon. The same way gold is a non luminous object.
A light is an open system. It runs on electricity, which enters the light from outside, and it emits light, which leaves. Energy is both entering and leaving the system all the time (at least, when the light is on).
It will be "blue-shifted". That is, the wavelength of the light will appear to be shorter and so more blue.
Yes. A star that explodes so that it emits thousands of times more heat and light than normal is a nova. If a nova emits as much as a whole galaxy it is termed a supernova.
Galaxy redshift is much light the Doppler effect. If a galaxy is traveling away from us, the light that it emits and is seen by us is stretched out (the faster we are separating, the stronger the redshift), that means that the wavelegnth is stretched a bit, shifting the light towards red.
No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.
is a type of chemical when exposed to radiation emits visible light.
The stars that you see at night are part of our Milky Way galaxy, which contains billions of stars. Each star you see is a sun-like star that emits its own light, and they are at various distances from Earth.

A type of galaxy is probably the answer you are looking for. However, a quasar is actually an active galactic nucleus.
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
A large celestial body that is composed of gas and emits light is called a star.
it reflects
It is a star, so it emits light.
