Field notes
The interface groups exploration into discoveries, missions, a daily challenge, an atlas, and step-by-step lessons. Its time control offers several scales, from days to millions of years per real second, while probe reports and options to follow or ignore objects suggest multiple ways to inspect a changing system. The page also says visitors can save an image or share a universe code.
