As you read this excerpt from "Fold Here: Scientific Uses for an Ancient Art Form," notice how the writer tries to make a difficult concept easier for the reader. While the human body remains a mystery even to scientists who study it their entire lives, it is not the only far frontier. Astrophysicists find outer space equally difficult to explore and explain, and they too have considered practical and technical uses for origami. A team at San Bernardino Valley College in Southern California created Starshade, a large structure that looks like a sunflower and acts like a pair of sunglasses: By blocking out a star's overpowering rays of light, the device helps a telescope produce a clearer image of the planets that orbit the star.

What analogy is used in this paragraph?

Starshade was created by a team at San Bernardino Valley College.

Starshade acts "like a pair of sunglasses" by blocking out light rays.

Astrophysicists find it difficult to explore outer space.

The human body is still a mystery to most scientists today.
