Gold-covered Telescope

The universe's biggest space telescope is as tall as a three-story building and as wide as a tennis court. Its main mirror, a collapsible honeycomb of 18 gleaming, gold-covered hexagons, is large enough to collect light from the very first, most distant stars and sensitive enough to capture the heat signature of a bumblebee on the moon.
