A type of wave that can travel through empty space as well as through matter is electromagnetic wave.
A longitudinal wave propagates through compressions and rarefractions, which would require a medium. Space is empty and therefore provides nothing to compress and rarefract, which is why you don't hear sound (longitudinal waveform) in space, because a sound wave cannot travel through it.
