Sister stellar systems

Filed under: Letters from Ionia — Tags: — zankaon @ 7:28 pm

Sister stellar systems, being of the same age, would have enough time for plant life, animalia (~650-1000 Myrs?), and even culture to arise. Oxygen detection in the atmosphere via spectroscopy, would indicate life. Detection of reflections from objects in orbit about such close by exoplanets or especially for moons, would be consistent with current or past technological society. Satellites sent to such systems would take 30+ yrs.

Communication would be via optical flashes. Have we already put out our calling card (2 ?), via sunlight reflective orbiters about our Moon? One could plot orbits via optical flashes. Might another stellar system sent a satellite to our easiest target (caveat of hitting orbit), Jupiter? Might we find other objects than ours, in orbit around our gas giant? What if on board radar detected a non-metal surface for such object – such as a composite? TMM
