Eolomea

Eolomea is a 1972 science fiction drama film directed by Herrmann Zschoche, based on the book of the same name by Angel Wagenstein. The film was an East German/Soviet/Bulgarian coproduction.

==Plot== Authorities responsible for Earth’s spaceflight safety grow increasingly concerned over unexplained incidents at the "Margo" space base, where several ships and their crews have mysteriously disappeared over three days. Following a special session, the Institute of Space Research issues a temporary flight ban until the cause is identified. Professor Maria Scholl suspects that fellow scientist Professor Oli Tal is withholding key information. She arranges a private meeting and learns about an unusual phenomenon observed in the late 19th century by British astronomers: a mysterious light in the Cygnus constellation that appears every 24 years. Soviet astronomers, after the first space flights, hypothesized that the light could be an artificial signal, potentially a powerful laser probing the Solar System for signs of life.
