These logotypes were developed for the "Laboratory for the Study of Exoplanets," an on-line educational outreach program developed by the Smithsonian Astrophysical Observatory for use in high school physics classrooms. The top version appears on the "overview" and "for teachers" section of the site, emphasizing the science content--the study of planets outside our solar system. The lower treatment appears on seven "lab" pages--the meaty section of the site. The logotype's change in visual focus emphasizes the site's exploration-based, "laboratory" approach to science discovery and learning.
