Unscramble the Blue Letters

So what this picture isn't showing you are all the planets that we know about out there in space. But when we think about planets, we tend to think of faraway things that are very different from our own. But here we are on a planet, and there are so many things that are amazing about Earth that we're searching far and wide to find things that are like that. And when we're seacrnhig, we're finding anaizmg things. But I want to tell you about an amazing thing here on Earth. And that is that every minute, 400 puonds of hydrogen and almost seven pounds of helium eapsce from Earth into space. And this is gas that is going off and never ciomng back. So hydrogen, hlueim and many other things make up what's known as the Earth's atmosphere. The aesotmphre is just these gases that form a thin blue line that's seen here from the International Space staotin, a photograph that some astronauts took. And this tenuous veneer around our planet is what allows life to flourish. It protects our planet from too many impacts, from mteteroies and the like. And it's such an amazing phenomenon that the fact that it's disappearing should frighten you, at least a little bit.
