researchers could watch explosions from start to finish. All the way to the finish, huh? How long does it take for a supernova explosion to "finish"? 'Bout a week?

How do you call something "imminent" that happened millions of years ago?

The star, Bettelguese, in Orion, is a red supergiant that astronomers say is on the verge of becoming a super nova. By the "verge," I mean anywhere between now and a few million years from now. Some of them say, though, that Bettelguese is close enough that when it does become a super nova, it could bath the earth in lethal radiation.
That's not in the story. Just my comment.

Is the word "IMMINENT" correct?
From what I remember from HS science class 28 years ago, the nearest star is 4.3 light-years away meaning the light we see from it today left it way back then. If it exploded today we would not know about it until the light from the explosion reaches us in a few years. Being many of the stars visible in the night sky are 10, 15, 20 and more light years away if a star is about to go super nova, didn't it really happen long ago and we are just finding out about it?
OK, I'm being picky, but I'm just trying to defend myself a little. I didn't deserve that C+. It's not my fault they sat a girl who always wore tight sweaters beside me drawing my attention elsewhere besides the teacher. heheheheh

Does the lethal radiation travel at the speed of light? Like, if you see the explosion, you're already toast? Or should I stock up on lead underwear????.......or Reynolds Extra Heavy Duty Aluminum Foil?......for my hat.....

"How do you call something "imminent" that happened millions of years ago?" Because the speed of light is a finite quantity. So terms like "imminent" apply to our perception of time, not it's actual passing. Since information can only be transmitted so fast (c = 300,000 KpH, approximately), any events that occur at longer distances (in this case, as with all stellar events, much longer), we are made aware of these events long after they have occurred.
Every time you look up at the night sky and see the stars, you are looking back in time. In most cases, way back. Even when you look at the moon, you aren't seeing it exactly as it is right now, but as it was about 2.5 seconds ago. Same for the sun, except that's a time delay of almost 8 minutes.
Strange, isn't it?

Speed of light, yes. You'd be toast. I'm just hoping those guys are wrong. Either that, or it doesn't happen for at least another 100 years--after I collect my social security.

Great, just great.
So now do I buy a car or lease?

Being here in the thunderstorm state of Florida, I can "relate" to that.

I was going to add that I live in an area of short buildings and tall utility polls, mostly concrete. I have been directly under these polls when they were struck by lightening on several occasions.
The first time was late at night, in pouring rain, and was quite a shock. The other day it happened in daylight, and was routine. Of course I was in car at the time.
