A light-year is the distance light travels in a year. It is equivalent to about 9.5 x 1012 (that is, 9.5 million millions) kilometers.
Light travels at 299792458 meters per second in a vacuum.
Self propagating electro-magnetic waves. Otherwise known as light waves.
Light travels in vacuum but sound cannot. So, we can see solar flares but can't hear them. (Outer space can be considered to be vacuum)
Light travels fastest through a vacuum, such as outer space. In other mediums, such as air, water, or glass, the speed of light is slower due to interactions with the atoms and molecules in the medium.
Light passes through the vacuum of outer space as it travels from the sun to the Earth. It does not require a medium such as air or water to propagate.

Hi, What has air got to do with the question? Light = photons, photons have no dependancy on air. Light travels in/ through outer space - no air there.
Light travels as light energy. Light is a type of electromagnetic wave.
Yes, mirrors work in outer space. They reflect light just like they do on Earth. However, objects placed in front of a mirror in space may not appear as they do on Earth due to the lack of atmosphere and different lighting conditions.
Light travels as light energy. Light is a type of electromagnetic wave.
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
