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 light years away. That means the light hitting your eye tonight has been traveling for 8.6 years. Put another way: When you look at Sirius tonight, you see it as it was 8.6 years ago.
