Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers - from the Sputnik and Explorer satellites launched in the late 1950's to the thrilling interstellar Voyager missions of the '70's - that yielded some of the most celebrated successes and spectacular failures of the space age. Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond.

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

During a classified mission to the ISS, astronaut Jack Kildare picks up an eerie signal. An alien spaceship is orbiting distant, icy Europa. It looks derelict...but is it?

The unabridged and enhanced 2nd edition of Zetetic Astronomy, formulated in the 19th century by Samuel Rowbotham, presents a flat-earth cosmology grounded in direct sensory observation rather than theoretical abstraction. Rejecting Newtonian and Copernican astronomy, Rowbotham argued that the Earth is a flat, stationary plane with the Sun, Moon, and stars moving in circular paths above it, asserting that empirical evidence—such as the apparent flatness of horizons and the behavior of water surfaces—supports this model.
