Tiny little shutters as small as the width of a human hair are a key component in the James Webb Space Telescope's ability to see huge distances in the cosmos, and they have now arrived at the European Space Agency. Those little "shutters" are actually called "microshutters" and they are tiny doorways that focus the attention of the infrared camera on specific targets to the exclusion of others. They will focus in on objects like very distant stars and galaxies.
