Outer space is not considered part of the sun's atmosphere. The sun's atmosphere consists of layers such as the photosphere, chromosphere, and corona, which are directly connected to the sun itself. Outer space, on the other hand, is the vast expanse beyond the sun's outermost layer, where the sun's influence diminishes.

ALL the energy given off by the Sun travels through space because if the sun has given it out, there is nowhere else it could go. Most of the energy is electromagnetic, with its peak intensity in the visible part of the spectrum.
The sun does not reflect its radiation into space.
