BearNap astronomy image sources and usage record
Reviewed: 2026-10-22

The ten JPEGs below are actual mission photographs or composites/projections
made from mission photographs. They were downloaded from official NASA image
servers at 640-pixel width and retained without local image edits. Processing
and composite-image limitations are recorded in the LT/EN image captions.

NASA image/media guidelines:
https://www.nasa.gov/nasa-brand-center/images-and-media/
NASA permits factual educational/informational reuse under its published
guidelines, with acknowledgement and without implying endorsement. This is not
a blanket licence for every file on a NASA website: separately identified
third-party copyright material has separate rights. No such image-specific
copyright reservation was identified in the selected captions reviewed here;
all listed mission-partner credits are retained.

JPL image-use policy:
https://www.jpl.nasa.gov/jpl-image-use-policy/
JPL's published policy permits reuse subject to attribution, non-endorsement
and its stated special cases. It also addresses educational reuse of
third-party material. This record does not claim every credited partner's
work is public domain or establish a blanket commercial licence.

Per-file sources and SHA-256 checksums: data/astronomy/image-sources.json in the
project source. Source pages, exact download URLs and retrieval evidence are
retained in the private research checkpoint.

The historic image's strong blue is enhanced, not an exact natural-colour
reference. Natural Uranus/Neptune colours are closer than this pair suggests.

Original SVG artwork

eris.svg, haumea.svg and makemake.svg are original BearNap project artwork,
constructed from vector geometry and gradients. They contain no downloaded
artwork or third-party texture. Rights remain with the project owner; this
notice does not grant a new public licence to third parties.

These three images are schematic illustrations, not photographs or measured
surface maps. Their shapes, lighting, colours and viewing angles are simplified.
NASA links identify scientific background, not the author of these SVGs.
Haumea is shown elongated with a narrow ring; Makemake has a representative
reddish-brown colour. No invented continents, craters or resolved ice fields
are presented as observations.

Neither NASA, JPL, Caltech nor any mission partner endorses BearNap. No agency
logo or identifiable person is included. Objects are not presented to scale.
