Documentary marking the fiftieth anniversary of Yuri Gagarin's flight into space. It was hailed by the Soviet Union as a triumph for socialist science over capitalism, but the true story is much stranger. George Carey's film shows how the Soviet space programme was kick-started by a mystic who taught that science would make us immortal, and carried forward by a scientist who believed that we should evolve into super-humans who could leave our overcrowded planet to colonise the universe. Stranger still, Carey shows how those ideas have survived Communism and adapted themselves to the science of the modern world.

Today Phil follows up last week’s look at the death of low mass stars with what comes next: a white dwarf. White dwarfs are incredibly hot and dense objects roughly the size of Earth. They also can form planetary nebulae: huge, intricately detailed objects created when the wind blown from the dying stars is lit up by the central white dwarf. They only last a few millennia. The Sun probably won’t form one, but higher mass stars do.
