The UMMO-Ciencias site
In January 1966 some strange letters began to arrive in Spain. Their senders claimed to be the members, on Earth, of an exploratory mission from the planet they called UMMO, 14.4 light-years from Earth.
These letters described, in some detail, the history and culture of the inhabitants of that planet UMMO. They also described the planet itself and its star system.
The philosophical, religious, scientific, technical, political-economic and other conceptions contained in these mailings were extraordinary for their originality and coherence.
After a first wave of letters in 1966 and 1967, addressed mainly, though not exclusively, to Mr Fernando Sesma, the letters became more spaced out in time and their recipients more diverse. In some years almost no letters were received, but they hardly ever stopped altogether, and in the second half of the 1980s a second wave of letters arrived, with even denser and deeper content.
Letters claiming the same origin, the beings of UMMO, have continued to arrive since then, both in Spain and in France.
On this site you will find the transcriptions of all the known letters, as well as facsimile copies of those originals we have been able to access. English translations are being added progressively; where one is not yet available, the letter links to the Spanish original.
Come in, read the texts, and judge for yourselves.
