Russian scientists expect humanity to encounter alien civilizations within the next two decades. “The genesis of life is as inevitable as the formation of atoms … Life exists on other planets and we will find it within 20 years,” said Andrei Finkelstein, director of the Russian Academy of Sciences’ Applied Astronomy Institute, according to the Interfax news agency.
Terrestrial Planet Finder- A planned Infrared interferometer for finding Earth-like extrasolar planets (as of 2010, it has not received the funding from NASA which it needs—that funding is going towards the Kepler mission).
Speaking at an international forum dedicated to the search for extraterrestrial life, Finkelstein said 10% of the known planets circling suns in the galaxy resemble Earth.
If water can be found there, then so can life, he said, adding that aliens would most likely resemble humans with two arms, two legs and a head. “They may have different colour skin, but even we have that,” he said.
Finkelstein’s institute runs a program launched in the 1960s at the height of the cold war space race to watch for and beam out radio signals to outer space.
“The whole time we have been searching for extraterrestrial civilisations, we have mainly been waiting for messages from space and not the other way,” he said.
