Therefore, in space, there is no air or other substance for sound to travel through, so astronauts and spacecraft cannot hear sound in the traditional sense. However, there are other forms of energy and radiation in space, such as electromagnetic waves and cosmic rays, which can be detected and measured by scientific instruments. **
