The world of visible light only reveals so much about the cosmos, which is why infrared and x-ray astronomy, for example, have proven to be so illuminating in modern astrophysics. Looking at the same galaxies and other cosmic structures in different regimes reveals new information that complements what we already know.The Chandra X-Ray Observatory has been exploring the "X-ray universe" since its launch in 1999 and is still going strong, beaming back astonishing x-ray images that ground-based telescopes simply couldn't "see," because the Earth's atmosphere absorbs the vast majority of those critical x-ray emissions. As a result, astrophysicists have learned a great deal about dark matter and supermassive black holes at the center of galaxies like Messier 87. But looking at structural patterns at different size scales can also be illuminating. That's the gist of a new online multimedia exhibit sponsored by the Chandra folks called ...
