Comparing other stars and planets tells us how unusual (or not) Earth is. That perspective matters for understanding climate, habitability, and even life itself.

Most of the imaging and signal-processing tech built for astrophysics ends up in medicine, satellites, and everyday devices. The "wow" factor funds a lot of spinoffs.

Space weather doesn’t stop at the edge of the Solar System. Supernovae, stellar motions, even rogue objects can affect us. Better to understand them early.

It’s long-term thinking. Nobody builds interstellar ships tomorrow, but mapping the neighborhood now is how future generations avoid starting from zero.

Honestly, it also grounds us. Realizing Earth is one small rock among billions changes how seriously we treat our only habitable home.
