What else can I help you with?
What is an Optical Telescope for?
It is used to observe features of stars, planets, and other celestial objects by their visible light (generated or reflected).
Do planets stars and comets shine as a result of reflected light?
Planets and comets shine because of reflected light because they do not produce their own light. Stars are enormous balls of gas that are undergoing fusion which releases a very large amount of energy in the electromagnetic spectrum which includes visible light. So stars shine because they produce their own light and not because they reflect light.
Which method has not yet detected planets around other stars?
Gravitational microlensing has not yet been used to detect planets around other stars. This method involves the gravitational deflection of light from a background star due to the presence of a foreground object, such as a planet, but no planets have been directly detected using this technique.
Does Mercury shine with its own light or reflected light from stars?
Mercury shines by reflecting light from just one single star: our Sun.
Planets do not light energy of their own?
Generally true, planets don't emit their own light, but are visible largely because of reflected light, the illumination provided by their star, in the case of our solar system, by the Sun. Some planets might produce trivial amounts of light by other means, for example from lightning, volcanism, mineral fluorescence, etc.
What is different about the light you see from planets?
Its reflected sun light - unlike the stars which generate their own light.

Are stars reflected light?
No. Stars emit light.
What is the source of all light in outer space?
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
Why are the planets visible even though they are not light sources?
other stars project light to planets reflects right to your eyes

Mercury shines by reflecting light from just one single star: our Sun.
How do planets and stars send light to us?
Planets reflect light from the sun. Stars emit their own light.
How do stars reflect light of planets and moons?
They don't. It's the planets and moons that reflect the light of stars.
Do planets give off more red light than stars?
No. The hottest planets might emit some infrared radiation (heat), but most visible spectrum light would actually be reflected from some nearby star. Stars range from 100 to millions of times as massive as the largest planets, and they shine through the light of nuclear fusion.
