To determine the true age of the Earth, geochemist Clair Patterson developed the uranium-lead dating method to make an unprecedented discovery - calculating Earth's age of 4.5 billion years. But Patterson's groundbreaking discoveries were just beginning. Patterson made it his mission to draw public attention to the detrimental effects of lead in the environment and dedicated his career to fighting against the petroleum and chemical industry, eventually achieving public health's biggest victory of the 20th century.
Astronomer Shep Doeleman and his team are on a mission that will challenge the theories of Albert Einstein and could pave the way to a revolution in physics: to capture the first-ever image of a black hole. To do this, they must link eight multimillion-dollar observatories around the world to a spot 26,000 light years away. It's the equivalent of spotting an orange on the moon, but after 10 years of planning and the combined brainpower of over 200 international scientists, the team feels they're ready to make scientific history.
