"Science" changed, and will continue to change to incorporate things once not considered possible.

For a while, transmutation of one element into another was impossible (Aristotle), then it was theoretically possible but never accomplished (classical alchemy), then it was shown to be impossible (Lavoisier), then it was observed.

Likewise it has become possible to observe, then predict, and now explain astronomical events. "What is the Sun made of?" is a scientific question now. Likewise "what is our destiny?" may be a scientific question in the future.
