Question

How eclipse is important in the study of science

Answer 1

Nowadays they're pretty much irrelevant.

In ancient times, eclipses (both solar and lunar) spurred thinking on the geometry of the solar system: What the heck is going on that causes the moon and the sun to disappear periodically? Is there a pattern to it? Why? And why are the eclipses always circles? Does that mean that planets and moons are spherical?

In modern times, solar eclipses aid study of the sun's corona, but lunar eclipses are pretty useless - they don't tell us anything we don't already know, and they don't allow us to study anything we can't otherwise study
