Going to the heart of the galaxy might not be dissimilar to going to an amusement park.

The rides are somewhat similar to how the stars orbit the center of the galaxy.

Ten million miles per hour, compared to, say, our sun, is about a factor of 50 times faster.

So something has to be going on at the center of our galaxy to make that happen.

But figuring out what is no small task.

The heart of our galaxy lies 26,000 light-years away.

It's difficult to observe through the vast amounts of stars, gas, and dust.

And there's another problem even closer to home: the Earth's atmosphere.

The atmosphere is great for us.

It allows us to survive here on Earth, but it's an absolute headache for astronomers.
