Interstellar migration

Cheerful salutations to all of my terrestrial friends! Did you know that a great number of your human scientists believe that some tiny organisms can easily migrate through space? I did! Some such organisms have been discovered and documented, like the adorable little tardigrade, otherwise known as water-bears.

The actual water bears are sillier looking and less geometrical than the critters in the image below. This image is meant to depict undiscovered organic structures of extra terrestrial origin, hitching a ride on cosmic winds towards distant worlds.

The tardigrade can survive extreme temperatures, has no need of sustenance for lengthy lapses of time, and can even withstand the harsh vacuum of outer space. Is it such a stretch of the imagination to believe that other similar organisms could exist? What would they look like? What incredible traits could such beings possess? Finally, could such hearty space travelers migrate across vast distances, and somehow still be alive to transplant their genetic material to other planets?

How long have such beings existed, patiently drifting through space, seeding life across the universe?
