/geo/sun
Get sunrise, sunset, solar noon, and civil/nautical/astronomical twilight times for any location and date. Returns all times in UTC. Useful for photography apps (golden hour planning), outdoor activity schedulers, smart home lighting automation, religious observance apps, and solar energy production estimates. Especially relevant in Nordic regions with extreme daylight variations.
/lightpollution
Get an estimated Bortle class (1-9) for any location based on nearby population density. This is an estimate, not a satellite measurement - it uses weighted population within 100km to approximate sky brightness. Returns Bortle class, sky quality rating, estimated naked-eye star count, SQM (Sky Quality Meter) estimate, and aurora viewing suitability. Accurate for major cities and remote areas; less precise for suburbs. Useful for astronomy apps, aurora tourism, astrophotography planning, and dark sky awareness.
/nasa/apod
Get NASA's Astronomy Picture of the Day (APOD), featuring a stunning space image or video along with a professional astronomer's explanation. Optionally specify a date to retrieve past entries. Running since 1995, APOD is one of the most popular science outreach programs. Ideal for science education apps, daily content feeds, desktop wallpaper apps, and space enthusiast communities.
/nasa/asteroids
Get a list of asteroids making close approaches to Earth today, from NASA's Near Earth Object Web Service (NeoWs). Returns asteroid names, estimated diameters, closest approach distances, relative velocities, and whether they are classified as potentially hazardous. Useful for space awareness apps, science education tools, and astronomy dashboards that track objects passing near our planet.
/nasa/mars
Browse photos taken by NASA's Curiosity rover on Mars, organized by Martian sol (solar day). Returns image URLs, camera names, and earth dates for each photo. Specify a sol number to browse different days of the mission. Useful for space exploration apps, educational content, Mars visualization projects, and anyone who wants to see the surface of another planet through real NASA cameras.
