| Description |
English: Top-down and edgewise look at some unbarred spirals. Time progresses from left to right, with earlier/younger appearance at the left, and later/older appearance at the right, approaching or reaching lenticular stage. Galaxies not necessarily to scale. By my understanding, the older, rounder ones are typically much larger than their younger forms.
Photoshop has a new symmetry mode which I made heavy use of to draw these. I also discovered that I am terrible at drawing logarithmic spirals myself, so I made use of an online graphing tool to get the curves right. |
