New paper: The possibility of panspermia in the deep cosmos by means of planetary dust grains (arXive pre-print, 2024)

The actual paper, at only four pages, is quite short. The Science Alert article may be more to your taste however if you don't have a math-heavy background. I'll suggest skimming both.
Two completely different approaches, and not exactly looking at the same question either, have come to complementary results nonetheless. It would not surprise me at all if biosignatures are found in nearby solar systems over the next decade or two. It may well turn out that life finds a way, and in a most unexpected way.
