One name.
Many possible skies.

How is this different from Real Sky?

Real Sky uses one frozen astronomical alphabet: every supported letter has one permanent star and every name traverses the same field.

Found Sky instead looks for an approximate realization of the name’s fixed geometry in other catalogued fields. Repeated letters still return to the same selected star.

A Found Sky result is a geometric realization. It is not a recognized astronomical constellation and does not imply that a name has a privileged or natural location in the sky.

The search stays on your device.

The browser searches versioned static sky data served by Name Constellation. Your name is not submitted to HYG, an astronomy API, or another remote provider.

Different viewing priorities can favor geometric similarity, brighter stars, named stars, or wider fields. These are presentation choices, not claims about a name’s astronomical meaning.

Shared fields stay reproducible.

Shared Found Sky links retain enough versioned state to reopen the selected realization consistently rather than silently replacing it with a later search result.

The link is reversible encoding, not encryption. Anyone with the complete link can recover the name and selected field state. The fragment is not part of the normal HTTP page request.
