Picture from the Mount Wilson Observatory Is the amazing solar system sized bubble in Cygnus discovered by Dave Jurasevich of the Mount Wilson Observatory , a Planetary nebulae or is it a Dyson sphere or a dyson Bubble ? In fact it is not a Dyson sphere or a Dyson bubble. Astronomers and physicists can tell the difference. But the bubble inspires speculation. What if it were a Dyson sphere in construction? From an article in the New Scientist on the dog day of 23rd July: "Giant Soap Bubble Found Floating in Space" It seems far too symmetrical. There are a number of ways we are supposed to detect extraterrestrial life. One, of course is from radio signals like the "WOW" signal , never to be repeated, emanating from the Chi Sagittarii star group. But another way was suggested by Dyson's thought experiment: Instead of radio signals look for Dyson spheres , which are artificial mega structures that enclose the orbit of a star, fabricated from the material of t
