The sunlight you feel is already old

The sunlight warming your face left the Sun about eight minutes ago.

Light is the fastest thing there is: 300,000 kilometres per second. But the Sun is so far away — 150 million kilometres — that even at that speed it takes a little over eight minutes to arrive.

That means that if the Sun went out right now, we would keep seeing it shine for another eight minutes. We are always looking at a sky that already was.
