The correct answer is 10 years into the past. Because of the finite speed of light, when you gaze up into the night sky, you are looking into the past. The bright star Sirius is 8.6 lightyears away. That means the light hitting your eye tonight has been traveling for 8.6 years. As you look at more distant objects, the effect becomes bigger and bigger. The Andromeda Galaxy is the most distant object readily visible to the naked eye. It is 2.5 million lightyears away. The light from it that we see right now is 2.5 million years old. We are therefore seeing the Andromeda Galaxy as it was at a time long before modern humans existed.
