Did you know that our Solar System is a rarity with its single star? Astronomers believe that most star systems out there actually contain 2 or more stars – imagine seeing a sky with 4 suns. These binary and multiple star systems are a great target for new astronomers, and the dynamics of multiple stars keep astrophysicists busy too. Let’s take a look at what it would be like to live on Tatooine – a good movie version of a planet orbiting binary stars.

Astronomy is one of the scientific fields that have been completely shaken up by new media. The Internet has enabled communication between researchers in a dramatic new way, creating new collaborations, removing obstacles, and drawing in an army of enthusiastic volunteers to help with research. Let’s take a look at how new media is helping change astronomy, and how you can get involved.

For those non-scientists trying to get their original ideas accepted by the scientific community, you’ve got to have thick skin. It might seem like there’s a vast conspiracy, or a general attitude that drives away original, but unorthodox ideas. But that’s not true, the reality is that great ideas in science come from everywhere, even amateurs. In this episode we’ll help you understand what scientists will be looking for, and the best ways to be taken seriously.
