Unscramble the Blue Letters

Now, most arsmtnoroes have a fovirate star, and mine today is a star that's lbeeald up there, SO-2. Absolutely my favorite star in the world. And that's because it goes around in only 15 years. And to give you a snsee of how sorht that is, the sun takes 200 million years to go around the center of the galaxy. Stars that we knew about before, that were as close to the center of the galaxy as possible, take 500 years. And this one, this one goes around in a human lifetime. That's kind of profound, in a way.

Now, most astronomers have a favorite star, and mine today is a star that's labeled up there, SO-2. Absolutely my favorite star in the world. And that's because it goes around in only 15 years. And to give you a sense of how short that is, the sun takes 200 million years to go around the center of the galaxy. Stars that we knew about before, that were as close to the center of the galaxy as possible, take 500 years. And this one, this one goes around in a human lifetime.
