Because there is nothing to stop it. Light has wave (EMW) and particle (photon) characteristics. Everything travels easier in a vacuum except sound as sound is a vibration and requires a medium to travel through. Light does not.

In order to understand this issue, we have to be clear that light is not a thing, but a series of changes in the values of an electromagnetic field, this changes travel through the space simply as that, variations of magnetic and electric fields. So they do not need to use any carrier.

Any celestial body and rocket can travel through a vacuum. So can light.
