What you see in this amazing video really is just a coincidence. A comet smashed into one side of the Sun just as a massive explosion ignited on the other side. Two entirely unrelated events...but they sure look awesome together.
We've seen some videos of comets smashing into the Sun before, but this video is on another level entirely. Not only is this the clearest view yet of a comet's final approach before crashing into the Sun, it's also followed by a huge coronal mass ejection on the other side of our star. Again, it's all a coincidence that one happened right after the other - these are simply two relatively common events that just happened to line up perfectly, and the results are nothing short of spectacular.
