Xeno is an open, single-page archive of humanity's documented encounter with the unexplained in the sky — the official record and the human record, gathered in one place and linked to the source.

Two things that usually live apart sit side by side here. The official record: verified government UAP/UFO disclosures from more than twenty nations — the U.S. PURSUE releases and the Navy videos, the UK MoD vaults, France's GEIPAN, Brazil's Air Force files and more — each card linking to the releasing body's own primary source. And the human record: tens of thousands of individual citizen and pilot sighting reports, plotted on a phosphor world map and a draggable 3D globe, searchable by region, shape and decade, and now carried as full narratives rather than one-line fragments — including every GEIPAN case, translated into English.

Nothing here is hosted speculation. Every landmark case links to the agency's own words; every status label reflects that body's own stated conclusion. No verified government release to date has concluded extraterrestrial origin — Xeno's job is simply to put the real material in front of you and let you read it for yourself.

Why “Xeno”?

The Greeks used xénos for anything outside the known — the outsider at the gate, the foreign, the unfamiliar. English inherited it as the prefix behind a whole family of words for the strange and the other:

• xenon — the noble gas William Ramsay named in 1898 from xénos, “the strange one,” because it was a rare, strange element hiding in ordinary air.
• xenobiology / xenoarchaeology — the literal scholarly names for the study of life and artefacts not of this Earth.
• xenolith — a “strange stone,” a fragment of foreign rock trapped inside another; xenophile — one drawn to the foreign.

Its deepest root, the Proto-Indo-European *ghos-ti- (“stranger, guest, host”), is also the ancestor of the Latin hostis and the English guest and host.

We chose it for three reasons. Accuracy — the subject of this archive is, by definition, the strange and the unidentified, the phenomena that don't yet fit the known. Xénos names that precisely, without smuggling in “alien” as a foregone conclusion. Lineage — xenobiology and xenoarchaeology place this work in a tradition of disciplined curiosity about the beyond, rather than folklore. And posture — to the Greeks, xénos also meant the guest. Their sacred custom of xenia demanded that the stranger at your door be met not with fear but with hospitality, until you knew who they were.

Strange, foreign, different — and worth understanding. That is the posture Xeno tries to take toward the unknown: meet it with open evidence and an open mind.
