Heaven may refer to the physical heavens, the sky or the seemingly endless expanse of the universe beyond. However, the term is often used to refer to a plane of existence (sometimes held to exist in our own universe) in religions and spiritual philosophies, typically described as the holiest possible place, accessible by people according to various standards of divinity, goodness, piety, etc. In most pious religions, you go to heaven after you die if God is pleased with your performance in life.
