Just think about it for a minute. The Hubble is the size of a large bus, travels at 17,500 miles per hour and is 370 miles above the Earth's surface.
How do you point it at a tiny speck in the universe millions of light-years away and hold it steady, sometimes for hours at a time, so it can take a picture?

Hubble has a sophisticated system that controls its position 24 hours a day. Its called the Pointing Control System.
