NASA Caught the First Glimpse of the Solar System's Stunning TailEric Limer7/10/13 1:46pmFiled to: SpaceSolar systemibexsatellitescomets192EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkThe solar system isn't stationary; it's careening through the infinite abyss of space as we speak. Just like a comet, it comes complete with its own tail, and for the first time, we've actually been able to see it. The new data is thanks to NASA's very own Interstellar Boundary Explorer (IBEX), which has been sitting thousands of miles out from Earth, painstakingly mapping the edges of the solar system. IBEX watches for formerly-charged deep-space particles that crash into the heliosphere's outer hydrogen atoms and come shooting back towards us. And by mapping out three years-worth of those suckers, IBEX has whipped up the first, pixelated images of what our tail looks like.
