About 7500 years ago the star system which is now known as Eta Carinae violently exploded. Because of its distance to earth it was not until the mid 1800's that the light from this explosion reached us. This explosion formed what today is known as the Homunculus Nebula. Scientists and NASA researchers lacked a keen understanding of the shape and details of the nebula. They have used 3D technology, however, to further develop their understanding of it. They have since 3D printed out a model of the Homunculus Nebula, allowing them to hold a miniature version of it in their hands, and develop an understanding of the way it appears from every angle. More details one this amazing use of 3D printing tech can eb found here: http://3dprint.com/8765/homunculus-nebula-3d-printed/

Below is an image of the actual 3D print of the nebula. What do you think?
