描述1e17m comparison 100 light years nebula clusters.png |
English: Comparison of lengths and sizes with order of magnitude 1e17m: hundred light year radius shell with yellow Vernal Point arrow as radius and 10 light year circle at right; globular cluster Messier 5 in background; 12 light year radius Orion Nebula middle right; 50 light year wide view of the Carina Nebula bottom left; Pleiades cluster and Bubble Nebula (NGC 7635) with similar diameters each around 10 light years bottom right; grey arrows show distances from Sun to stars Aldebaran (65 light years) and Vega (25 light years). All distances and sizes approximately to scale. No transparency version. |

derived from Paul Stansifer's POV-Ray source files (see below), by me, 84user, using w:en:POV-Ray, and w:en:IrfanView. 84user's contribution (inside POV-Ray files: adjusting coordinates, changing light source and other parameters) is public domain and source files used are described at User:84user/Size comparison. Physical information is based on the Wikipedia articles and elsewhere (see POVRay source files) about the respective lengths. Paul Stansifer's contributions to this image (POV-Ray code) are available under the GPL, v. 2, and other licenses. See User:Paul Stansifer/Size comparison for more details and the other licenses. |
