Sky Lights

On desolate mountaintops in Hawaii, Arizona, and Chile, a group of billion-dollar super-telescopes is about to expand the boundaries of what we can see in space. The language used to express these accomplishments may seem like hieroglyphics. How many people will understand the technical meanings of "magnitude" and "arc second"? But what really matters is that we'll be able to spot fainter stars and galaxies, and they'll appear sharper than ever before.
