Carl Sagan Day
Today is the 75th birthday of one of the greatest popularisers of science we have seen. Sadly he died in 1996 and is not around to share it with us. Presenting the seminal TV show Cosmos in the 1980s Sagan made this moving statement about our place in the universe, how tiny and insignificant we are on the cosmic stage, how petty our squabbles, and therefore how important it is that we look after the only home we have ever known, and the other humans we share it with.
