Today is a really big day here at the for because we finally finished building our brand-new observatory. Now we can learn even more cool stuff about space. Let's fire up the new telescope, Squeaks.

*Squeaks squeaks*

Ah, you're right, Squeaks. It does look a little bit blurry. While Squeaks and I fix the focus on our telescope, check out this episode for a refresher on what stars are and why they shine. 

If you're like us here at the fort, you probably enjoy stargazing. The night sky is full of cool things to look at and I bet a lot of you have been looking up there and wondering about the same things that we do. We've gotten some really interesting questions from kids like you about what you see up there.

Eight-year-old Alice from New Zealand has been doing some sky-watching and she recently emailed to ask us, "What are stars and how do they work?" Let me just say that's a stellar question. If you look up at the night sky all the stars that you see might look pretty similar, but don't let your eyes fool you. All of those stars have some important things in common, but they're also all different. They can be different colors like white, yellow, red, and blue. They can also be different sizes from about the size of a planet to something many, many times bigger than the Sun.

But before we meet some of the extreme stars, let's figure something out first: what exactly is a star? Stars are just really huge balls of hot gas in space, and deep in their centers, all stars are constantly generating an enormous amount of energy. This energy eventually travels out from the center of the star where it's given off as heat and light. That's what gives stars their glow. So keeping in mind that all stars are balls of gas that come in all kinds of sizes and colors, wanna meet some for yourself? 

Let's start with the most important star, at least for us here on Earth, the Sun. That's right the Sun is a star, and it's a specific kind of star called a yellow dwarf. While we think of our Sun as being super huge and incredibly hot, which it definitely is, compared
