" Once a moon is found, the next obvious question would be: Does it have an atmosphere? If it does, those gases will absorb a fraction of the star's light during the transit, leaving a tiny, telltale fingerprint to the atmosphere's composition. The signal is strongest for large worlds with hot, puffy atmospheres, but an Earth-sized moon could be studied if conditions are just right. For example, the separation of moon and planet needs to be large enough that we could catch just the moon in transit, while its planet is off to one side of the star."
A jeszcze więcej smaczku dodaje informacja, że bycie czerwonym karłem dla gwiazdy centralnej wręcz ułatwia zadanie:
" (...) tidal locking could be a problem for red dwarfs. A planet close enough to be in the habitable zone would also be close enough for the star's gravity to slow it until one side always faces the star. (The same process keeps one side of the Moon always facing Earth.) One side of the planet then would be baked in constant sunlight, while the other side would freeze in constant darkness. An exomoon in the habitable zone wouldn't face this dilemma. The moon would be tidally locked to its planet, not to the star, and therefore would have regular day-night cycles just like Earth. Its atmosphere would moderate temperatures, and plant life would have a source of energy moon-wide. Alien moons orbiting gas giant planets may be more likely to be habitable than tidally locked Earth-sized planets or super-Earths."
A wiecie co to oznacza? Oznacza, że tekst: "Na Proxima Centauri , II klasa w jedną stronę" może być bardziej prawdopodobną wizją przyszłości niż się to na pierwszy rzut oka wydaje.

Cały problem w tym, ze bez tych "złych ludzi" co budują fabryki, nie było by statku zdolnego zawieźć "tych niektórych" na księżyc gdzie rosną warkoczyki.
