Because you might have seen it in a telescope years ago idk
Another Answer
A light year is a measure of distance. If an object is 15 million light years away, the light you are looking at in this moment was produced 15 million years ago. If a star that far away went supernova at this moment, we wouldn't know it for another 15 million years.
The light we see on the surface of our planet from the Sun is a little over 8 minutes old, because it took that light about 8 minutes to travel from the Sun to Earth.
