Why there is no morning and evening in space?

In space, there is no atmosphere to scatter sunlight, which means that the sun's light is not diffused as it is on Earth. As a result, when an object in space is in direct sunlight, it experiences constant daylight, while objects in shadow are in perpetual darkness. This lack of atmospheric interference eliminates the gradual transition from morning to evening, resulting in stark contrasts between illuminated and shadowed areas. Thus, time markers like sunrise and sunset do not exist in the same way they do on Earth.
