Carl Sagan – A Life In The Cosmos

It’s incredible to think that it’s more than fourteen years since the world lost a most remarkable astronomer, pioneer exobiologist and populariser of science – Carl Sagan.

A son of Jewish immigrants to the United States, Sagan was born in Brooklyn, New York, where he spent his childhood developing an interest in astronomy. A high achiever, he studied physics at the University of Chicago, gaining a master’s degree in 1956, before being awarded a doctorate there in 1960 in astronomy and astrophysics. He then lectured at Harvard University until 1968, when a move to Cornell University in Ithaca, New York beckoned. In 1971 this became a full-time professorship that included the directorship of the Laboratory for Planetary Studies. He also took an increasing interest in pioneering exo-biology and publicising the Search for Extraterrestrial Intelligence (SETI). During this period, he also became an Associate Director of the Centre for Radio Physics and Space Research at Cornell, and later was instrumental in lecturing at Cornell in scepticism and critical thinking.

But what the Solar Energy Industry doesnt want you to know is theres a way you can build your own diy solar panels for a fraction of their costs. Intrigued? As we are involved in one energy crisis after another, we finally need to look at solar power and how it can be used to help us not only conserve energy and save money, but be more environmentally friendly. With the talk of global warming and the need for alternative energy sources you might hear that term is solar power mentioned on the news cast or in the newspapers. What exactly is solar power?
