Well, one possible way the Earth could be destroyed is shown in this beautiful video backed musically by, appropriately enough, Pink Floyd's Dark Side of the Moon. I especially like the way the huge mass appears to hit the Earth in slow motion, which of course is how it would look like that due to the size, even though the shock wave would be moving supersonically. Watch, enjoy and be afraid.
The lovely photograph here was taken using a 10.5mm fish eye lens by the photographer John Colbenson and looks like it was from the space station. Just shows you what you can make even on a normal flight somewhere. Have a look at his work, you will see some exquisite landscapes.
