Are there any practical uses for astrophysics?

Or it is only science for science, without any real world applications?

There are some real-world applications that have come out of astronomy. Communication satellites are pretty obvious. GPS wouldn't work if we didn't take relativity into account. But there are other indirect advancements - digital cameras got a big boost from developing fancy telescopes.

But yeah, mostly it's more of a philosophical thing: knowing our place in the universe, understanding where we came from and what will happen in the future. If we live in a solar system, in a galaxy, in a universe, then it's probably worth knowing what those things *are* exactly...
