Tornadoes, hurricanes, snowstorms, lightning and floods – for us these destructive forces are symptoms of Earth's creative energy. The weather on Earth is one of the drivers for life and even the most violent and destructive storms create new opportunities for life to flourish. In our quest to discover if we are alone in the universe, we have recently hit upon a surprising new approach — we shouldn't just look for worlds, we should look for weather. What is true of Earth could also be true of other planets throughout the whole universe. Across the immense distances of space, find chaotic weather — find that megastorm — and maybe we will find alien life.
The universe is unbelievably big – trillions of stars and even more planets. Soo… there just has to be life out there, right? But where is it? Why don’t we see any aliens? Where are they? And more importantly, what does this tell us about our own fate in this gigantic and scary universe?
New discoveries are challenging everything we know about black holes -- astronomers are beginning to question if they even exist. The latest science tries to explain how they work & what they look like, despite the fact we've never actually seen one.
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.
