Webb has been orbiting more than a million miles from Earth, capturing breathtaking images of deep space. But how does it actually work?
Next time you're drinking a frosty iced beverage, think about the structure of the frozen chunks chilling it down. Here on Earth, we generally see ice in many forms: cubes, sleet, snow, icicles, slabs covering lakes and rivers, and glaciers. Water ice does this thanks to its hexagonal crystal lattice. That makes it less dense than nonfrozen water, which allows it to float in a drink, in a lake, and on the ocean.
