A new article by Tammy Plotner in Universe Today:
I turned this Hubble Heritage image of the "Ring Nebula" to the Spatial format.

Distances and shapes in 3D-image are visualizations, since we don't have enough information to buil an accurate model. However, the 3D-model of the target is not only a lucky guess as there is many known "anchor points" in the image, witch can be used to estimate the actual forms and the relative distances.

A Starless version to show the nebulosity better.
