Doctored 3D Models Of The Rosetta Comet Are the Best

As the Rosetta spacecraft acquires more precise measurements of the comet 67P/Churyumov-Gerasimenko, scientists are able to create detailed 3D models. Last week, the ESA made that data available for downloading, allowing people to make their own comet replicas—sometimes, with a few creative embellishments. » 10/09/14 11:47am 10/09/14 11:47am
