Obviously, this site will be and is a bit of an experiment. One of the inspirations for this older 'frames' view of my notes is , or maybe was, the particular site referenced here --> [[1]] That site uses dynamic sidenotes. [[2]] I think having viewable and dynamic sidenotes is a fascinating means to understand specific material and jump back and forth to the core. ^004837
This is a test. How S0 galaxies form is unique. This is the display
Test Topic -- When viewed edge-on, S0 galaxies (alternatively called lenticular galaxies) have a shape reminiscent of a lens (hence the alternative name). Located at the fork in the Hubble classification diagram and labelled S0 or SB0 (if there is a hint of a bar), they have a structure that appears intermediate between elliptical galaxies and spiral galaxies.
