The Sunday letter

One email a week, on Sunday morning. It takes about five minutes to read and leaves you with something to think about for the rest of the week.

Each letter includes:

The stories we published that week, with a line from the editor on why each one matters.
One piece from elsewhere, a paper, essay or archive find, that we could not stop thinking about.
What to look for in the night sky this week, written for people with nothing more than their eyes.
