Astronaut Tim Peake steps away from the planets in our solar system and explores the stars beyond. He unravels the mystery of what stars are made from, how long they live, and what happens when they eventually die. At the center of our solar system is our star, the sun, and Tim travels to the shores of Western Australia to witness a truly spectacular event, a total solar eclipse.

Life in space isn't easy. Tim Peake knows because he had to go through six years of training before his trip to the International Space Station. Once he left earth, one of the most daunting moments of any mission is heading outside for your first spacewalk. Tim visits the European Space Agency in Cologne and explains how you survive when you're floating 400 kilometers above the earth.
