Image and mission credits

Object detail windows include source links for images and mission references. To keep Celesiq fast and reliable, object photos are intended to be cached locally instead of hotlinked from third-party image servers. The source links point visitors to official mission pages, public image releases or educational references. If an image credit needs correction, please use the contact page so the source can be updated.

Calculation note

The map and event tools are approximate and optimized for visual explanation. They should be checked against official ephemerides or mission data when exact predictions matter. The solar-system map includes a developer validation script that can compare the local planet positions with JPL Horizons vectors.
