Is it true the light we see from the sun and stars is millions of years old?

Answer 1

Sun is comparatively near. The light from Sun left 8.2 minutes before we see it.

The light from the stars in the Andromeda galaxy is 2.5 million years old. Light travels slowly; its speed is 300,000 kilometers per second. Many stars and galaxies are extremely far away from us.
