A 'light year' is not a time. It's a distance. Specifically, the distance that light travels
in one year.
So when you photograph a star that's located 10 light-years away from us, you
photograph the light that left the star 10 years ago. Your photograph records the
color, temperature, motion, and position of the star as of 10 years ago. If that
star were to explode today, you could not know it until 10 years from today.
