Field notes
The homepage organizes topics both by celestial subject and by the kind of question a reader has, with paths such as “Is that true?” and “How did we find out?” Its Moon model labels the light direction and current phase, while cautioning that the pictured scale is not realistic. The discovery notebook is described as browser-local, with a warning that clearing browser data can remove saved notes.
