The reddest stars are the stars that are considered the coolest. Blue light is more effectively scattered than Red light. This is called ``interstellar reddening".
The light from stars can tell us what type of star it is (our Sun is a G type), the stars spectrum can tell us what elements are in the star, and its intristic brightness can help us determine how far away it is. Also, if there is a wobble in the star, or a change it the stars brightness can tell us if it has a planet.
The spectrum is a kind of analysis of the light emitted by a star.
Didn't you ever see a star? - Light is a type of electromagnetic wave.

Mainly light and other electromagnetic wave.

Any type of Ivy are good for low light areas.
Type your answer here... yes they can because if they get squirted by an octopus it gives them a disease like that
Most stars have absorption spectra. In other words, stars possess thin outer layers that allow light to pass through. These layers produce what are called absorption lines. This means the light from the sun and stars are absorption spectra.

All stars emit light. However, people are not able to see some stars because of the different type of light the wavelengths produce. +++ Also of course, the received intensity depends on distance. A black hole would be incandescent too, but by its definition the light it creates cannot escape the objects immense gravitation.
"Optical" telescopes use visible light. But if they're used to observe stars, then their purpose is not to make the stars seem closer.
