NASA found the youngest supernova ever in our galaxy.
Don't ask me how I know -- I just know. This is the answer to the "mystery."
I won't elaborate and I won't divulge my sources. You'll just have to wait and see if I'm right.
I don't know if anyone has said this yet but Kudos to behindthescenes on this one.

I think that is a good point, it's all too easy to forget about relativity when we're talking about such huge distances.
The explosion occurred about 140 years ago, making it the most recent supernova in the Milky Way as measured in Earth's time
frame...

It might seem that all we need to do is translate what they mean to our relative frame of reference. To say the event happened 140 years ago we can
then translate that to actually mean that's when the light from the event finally got to Earth. Regardless this is an incorrect statement, confusing
at least, and still a good point by RedGolem IMO. I believe it is important to keep in mind that the farther we look out into space the further we are
looking back in time.
