Probably, since there are star explosions all the time. Please note that no information travels FASTER than light, so we have no way of knowing in advance, unless we see a star that is about to explode, and correctly guess this fact.

Why is it important to know how long light takes to reach the Earth?

Since light travels at a known speed and changes in frequency as it travels, it provides a way of measuring the distance to faraway stellar objects (stars, galaxies). This provides important clues to the structure of the universe. To the naked eye, dim nearer objects (asteroids, planets, stars) look the same as bright faraway ones (galaxies). Some distant stars and galaxies whose light reaches the Earth today no longer exist, at least not in the form they had when the light was emitted, many millions of years ago. As for the light from the Sun, its 8-minute travel time to Earth is an interesting concept, but has little bearing on how the Sun affects the Earth.

How do you replace rear tail light bulb on a 1985 corvette?

I have a 1988 and I answered in this forum before about changing the tail light and I think it is the same with the 85, The problem is the space is so small the average person's arm will not fit to get at the light. I used my 14 year old son whose are was alot thinner than mine and he was able to reach up and change the bulb. He had to squeeze his arm up until he could reach it it is a very tight spot.
