This is one of the most-famous astronomy photos in the world. Called "The Pillars of Creation" it was taken by the Hubble telescope in 1995 and shows massive columns of hydrogen gas and dust in the Eagle Nebula—7,000 light years from Earth. Part of why these are a big deal is that columns of dust and gas like this are places where stars form.
But here's a cool and/or disappointing detail I hadn't known about until today. Back in 2007, researchers took more images of this region of space using the Spitzer Space Telescope. These shots suggest that the Pillars of Creation might actually be long gone—destroyed thousands of years ago by a nearby supernova.
A 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.
Space is crazy, y'all.
