The issue, as correctly emphasized by Carl Sagan, is the probability of the evolution of high intelligence and an electronic civilization on an inhabited world. Once we have life (and almost surely it will be very different from life on Earth), what is the probability of its developing a lineage with high intelligence? On Earth, among millions of lineages of organisms and perhaps 50 billion speciation events, only one led to high intelligence; this makes me believe in its utter improbability.

NGC 3294 (Galaxy) Right ascension: 10h 37m Declination: 37° 15' Constellation: Leo Minor Date/time: 2015.04.18 22:00 UT Equipment: 12" f/5 Newtonian FoV: 23' Magnification and filter(s): 167x Seeing: 6/10 Transparency: 2/5 SQM: 20.87 m/as2 Temperature: 3°C Humidity: moderate Wind: breeze Sight: 2 - minor details, somewhat interesting Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details Position: 4 - hard, complex starhopping needed Location: Talpa Minor Observatory Observer: Ferenc Lovró Description: WNW-ESE elongated, almond shaped galaxy. Visible directly at an instant. Small, no stellar core visible. Its Northern half appears slightly brighter. I've observed this galaxy as a mistake, because I've already bagged it almost exactly one year ago: here. Seems that my logs are not really accurate and some of my observations may be missing from the "already observed" list of mine. :) Hi-resolution image: [ reversed sketch | original sketch ]
