Welcome to the first episode of Crash Course Astronomy. Your host for this intergalactic adventure is the Bad Astronomer himself, Phil Plait. We begin with answering a question: "What is astronomy?"
Today on Crash Course Astronomy, Phil invites you to head outside and take a look at all the incredible things you can see with your naked eye.
This week we build on our naked eye observations from last week and take a look at the cyclical phenomena that we can see at work in the universe.
In this episode of Crash Course Astronomy, Phil takes you through the cause and name of the Moon's phases.
Today Phil explains how telescopes work and offers up some astronomical shopping advice.

This visually stunning program chronicles a sweeping journey, from 1609 when Galileo revealed mankind's place in the galaxy to 2009, the International Year of Astronomy. Narrated by NOVA's Neil deGrasse Tyson, the compelling program takes viewers on an adventure through the heavens and around the globe, visiting the world's leading astronomers, cosmologists and observatories. The Interstellar Studios production team traveled the globe to interview leading astronomers and cosmologists from the world's renowned universities and observatories. The producers sought the most acute minds at great astronomical centers including the European Southern Observatory, Institute for Astronomy, SETI Institute, Space Telescope Science Institute, Anglo-Australian Observatory, and Harvard University. They journeyed across five continents to visually write the story of the past and the future of telescopes, astronomy, and our ever-changing perception of the cosmos. Compelling interviews throughout the film leave no stone unturned. A carefully chosen array of today's leading astronomers explain concepts ranging from Galileo's act of revealing the telescopic cosmos to humanity and challenging religious teachings of the day, to the latest discoveries in space, including startling new ideas about life on other planets and dark energy – a mysterious vacuum energy that is accelerating the expansion of the universe. On the horizon, viewers learn of emergent telescopes the size of stadiums. With unprecedented resolution and light gathering, these enormous new instruments will look back to the initial moments of the Big Bang and – like Galileo's first telescopic observations – will reshape our model of the universe.

Discover how beauty and order in Earth's cosmic backyard was formed from nothing more than a chaotic cloud of gas. Chasing tornados in Oklahoma, Professor Brian Cox explains how the same physics that creates these spinning storms shaped the young solar system. Out of this celestial maelstrom emerged the jewel in the crown, Brian's second wonder - the magnificent rings of Saturn.
