Początki naukowego udowodnienia hipotezy panspermii sięgają końca XIX wieku. W latach 70 i 80tych XX wieku wysunięto twierdzenie jakoby komety były nośnikiem życia w przestrzeni kosmicznej. Spadki meteorytów: Murchinson, Orgueil czy Nakhla skierowały wzrok badaczy ku Marsowi, jako potencjalnie zasiedlonej przez mikroorganizmy planecie. W ciągu wielu lat badań chondrytów węglistych zaobserwowano wiele struktur, które swą morfologią i wielkością przypominają ziemskie bakterie. Pomimo tego nie znaleziono jednak niepodważalnych dowodów na istnienie pozaziemskiego życia.

The origins of scientific evidence of panspermia hypothesis back to the late nineteenth century. In the 70s and 80s of the twentieth century the claim that the comets are the source of life in space has been put forward. Fall of meteorites like: Murchison, Orgueil and Nakhla directed attention of researchers to Mars, as a planet potentially inhabited one time by microorganisms. Over the years studies of carbonaceous chondrites recorded many structures the morphology and size of which proved similar to those of Earth's bacteria. Despite this there is still no clear evidence for the existence of extraterrestrial life.
