Astronomy is different from other science because astronomers study stars, planets, different space rocks, etc. In matter of fact, all science is different from one another. There is astronomy, phsycology, and more! You'll never be able to guess all of them! So, astronomy is different from other science, just like other science is different from astronomy and so on. So, all science is different from one another.
