Frank Drake, a pioneer of the search for extraterrestrial intelligence (SETI), has warned that for any intelligent aliens trying to search for us, "the Earth is going to disappear" very soon because of the growing use of technologies that do not leak radio noise into outer space that extraterrestrials might be able to hear.
If intelligent life exists elsewhere in our galaxy, advances in computer processing power and radio telescope technology will ensure we detect their transmissions within two decades, says SETI Institute senior astronomer Seth Shostak.
Peter N. Spotts argues that better technology and robust funding is the required fuel to help in the search for intelligent life beyond Earth.
An interview with Dr. Michio Kaku on the physics of extra-terrestrial civilizations, and whether we can classify their evolution judging from our own work in progress.
The building blocks of life pervade the solar system, and probably the universe, locked up in planetary polar ice caps, crouching in the interstices of ancient volcanic rocks, zooming around on comets and meteorites, drifting between galaxies in interstellar space, or wafting gently down in cosmic dust.
Allen Tough argues that if extraterrestrial intelligent life exists in the universe then it will have sent probes out to look for life (similar to Voyage or the the Spirit rover). Seth Shostak looks at his argument and whether or not scientists should be looking for extraterrestrial probes.
One tenth of the stars in our galaxy might provide the right conditions to support complex life, according to a new analysis by Australian researchers. And most of these stars are on average one billion years older than the Sun, allowing much more time, in theory, for any life to evolve.
Richard Carrigan, Jr., a physicist at the Fermi National Accelerator Laboratory warns that scientiststs should think about decontaminating potential SETI signals to reduce the risk that the signals could carry harmful information similar to a computer virus.
The Search for Extraterrestrial Intelligence has finally gained acceptance both in scientific circles and in congress.
Walter Simmons, a physicist at the University of Hawaii, together with his colleague, Professor Sandip Pakvasa, have come up with a clever scheme that would allow interstellar broadcasters to keep the coordinates of their home planet secret by taking advantage of advances in quantum cryptography.
