Astronomy question: if a star in our sky explodes (we see the change tonight in the night sky) and the star is 1 million light years away...?
....does that mean it actually exploded 1 million years ago?

That's correct. The "News" of the explosion has been traveling for 1 million years - and finally got here just now, even though the event took place 1 million years ago.

I'm not exactly sure of the time frame that it takes light to travel that far but if a star goes Nova thousands of years ago you won't see the evidence of it here in the sky on planet Earth until the light reaches us which could take millions of years or thousands of years or hundreds of years depending on how far away the star is
