Thousands of astronomers are simply buzzing, eager to see the marvels that Webb might pick out of the darkness.

Many people’s experience of work over the past two years, amid a global pandemic, has been one of invasion: Their job has infiltrated the personal sphere, colonizing space that used to be distinct.
