I guess in a violent demonstration of the fragility and tenuous existence of things in nature, the subject of one of the most iconic images taken by Hubble, the three pillars of creation, has been destroyed. Or rather it was destroyed about 6000 years ago, it has just taken this long for the light to reach us. NASA and Hubble scientists using cameras linked to the powerful Spitzer telescope have detected that the pillars were super heated and then blown apart by the shockwave from a supernova blast. The nature of physics being what they are though, they will still be visible to generations of amateur astronomers to come using slightly less exotic telescopes :-)
