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.
One of the things I enjoy about writing for BoingBoing is the opportunity it's giving me to learn how to write reviews of books. That's not something I'd ever done before I started writing here. And I'm only now getting around to experimenting with not only describing books I like, but figuring out how to talk about books I find to be flawed. Fair criticism is a difficult skill to learn.
That's why I'm sort of simultaneously terrified and in awe of this 1991 book review, published in the International Journal of Primatology. In it, anthropologist Matt Cartmill expresses his opinions about sociologist Donna Haraway's book Primate Visions. I don't know enough about either scholar, or the book, to have an opinion about whether Cartmill is right or wrong. But, wowow, is that a blistering review.

This is a book that contradicts itself a hundred times; but that is not a criticism of it, because its author thinks contradictions are a sign of intellectual ferment and vitality. This is a book that systematically distorts and selects historical evidence; but that is not a criticism, because its author thinks that all interpretations are biased, and she regards it as her duty to pick and choose her facts to favor her own brand of politics. This is a book full of vaporous, French-intellectual prose that makes Teilhard de Chardin sound like Ernest Hemingway by comparison; but that is not a criticism, because the author likes that sort of prose and has taken lessons in how to write it, and she thinks that plain, homely speech is part of a conspiracy to oppress the poor.
