Well, it's not that hard to understand. It's due to the mioitatiln of the speed of light. Take a given star 100 light-years from here: you're seeing the star as it was a century ago. If it goes supernova, or turns into a red giant, or whatever, we won't know until the light put out under the new conditions reaches us, which takes a hundred years. Another example is quasars. They no longer exist but we still talk about them in the present, because the light from those super-distant but long-gone objects still reaches us.References :
