Dave Brody writes and directs Universe-themed non-fiction documentary television. There is much talk lately about cities on Mars, Numerous bases on the Probe, Unoccupied orbiting “islands” in Universe where tens of thousands of people might live and even Between stars generation ships. But what defines a Accurate community — as different from a Fundamental base … Read more
View larger. | Artist’s concept of the Wolf-Rayet 104 pinwheel Sun system. A new study confirms 2 massive stars are orbiting All other in this system, producing a giant spiral composed of hydrocarbon dust. The study also shows the poles of the stars are not oriented directly toward us as 1st thought, so there is … Read more
