enjoy them while you can!
Oh wait, i imagine the supernova occured a thousand light years closer to us than the nebula perhaps?
"A new, striking image from Spitzer shows the intact dust towers next to a giant cloud of hot dust thought to have been scorched by the blast of a star that exploded, or went supernova. Astronomers speculate that the supernova's shock wave could have already reached the dusty towers, causing them to topple about 6,000 years ago. However, because light from this region takes 7,000 years to reach Earth, we won't be able to capture photos of the destruction for another millenium or so."
Very interesting that.
