What are the advantages of sending an unmanned rather then a manned spacecraft to space?

Several advantages; mainly:A human needs food, air, and protection. An unmanned craft needs none of these; its use of energy and other "extras" is much less than for a human.An unmanned craft can be sacrificed; there is no moral obligation to return it safely to Earth.In summary, all this makes an unmanned spacecraft much cheaper than a manned spacecraft.

Why is most space exploration accomplished with spacecraft without astronauts?

The most obvious answer to your question is the fact that people have to return to earth, while an unmanned craft can stay in space infinitely. Manned spacecraft require things like oxygen, water, food and communications equipment, none of which are required by an unmanned spacecraft. That means unmanned spacecrafts can be sent into space for a fraction of the cost of a manned spacecraft. So basically, it's much cheaper and safer to send unmanned spacecrafts to explore the universe.

Why are most space explorations accomplished by unmanned shuttles?

This is because sending men up into space costs a lot more money than sending probes or other unmanned space craft. When you send a crew of people up you need to provide their living space, food, air, etc so they can survive. Holding all that would make the ship larger and cost more than a smaller unmanned ship. Also unmanned crafts can travel longer distances. No human wants to go on a 10 year journey where they might end up killed, these droids can do this for them.
