Does the sun shine in space and why?

Answer 1

OF course... the same reason other stars shine in space, they're stars! They have continuous nuclear reactions that emit TONS of light and energy.

Answer 2

Yes, the sun shines in space because it emits light and energy through a process called nuclear fusion. In the vacuum of space, there is no atmosphere to scatter or block the sunlight, allowing it to travel through space and reach planets and other objects.
