Exploring Alternative SETI Search Algorithms with the ATA

 As a novel, many-element interferometer, the ATA supports radically different observing modes than any single-dish, yet performs very well in single-dish mode using beamformers. The cutting edge technology of ATA allows simultaneous data processing in 3 different modes: spectral imaging, ultra-high resolution single-point observing, and high speed data capture. The latter mode allows the application of any algorithm you can imagine on time-series data.

Deep Space Flight and Communications: SETI, KLT and Astronautics in a 2009 book

Dr. Maccone's new technical book about SETI, KLT and space missions to the Sun gravity focus will be presented in this talk. This 400-page book is entitled "Deep Space Flight and Communications", costs (unfortunately) over $100, and is divided into two parts: (1) The first 200 pages describe the astrophysics of light-bending caused by the mass of the Sun. Since the minimal focal distance turns out to lie in between 550 and 1000 AU, any future space mission to exploit this effect must necessarily be a "deep space mission".

The search for intelligent life in the Universe: some great challenges for SETI

The union of space telescopes and interstellar spaceships guarantees that if technological extraterrestrial civilizations were nearby or common, then someone would have come here long ago. Dr. Ben Zuckerman will discuss how construction of telescopes such as NASA's proposed Terrestrial Planet Finder enormously strengthens the force of arguments against the existence of nearby intelligent civilizations.

The Implications of the Law of Accelerating Returns for the Search for ETI

 The law of accelerating returns (which states that the key measures of information technology progress at an exponential not linear rate) has important implications for our interpretation of the Drake formula and the likelihood of finding ETI's in our light sphere. Ray Kurzweil will present this special lecture for the Singularity University ( and the SETI Institute. 

Convergent evolution of our own and extra-terrestrial intelligence

Convergent evolution is the phenomenon of two or more species of widely different origins evolving extremely similar features in response to the same environmental opportunity. Our intelligence and that of aliens with whom we might communicate are likely to have converged considerably and to converge further in the future. Much of this future convergence is likely to be artificial, i.e. electronic. Professor McCarthy will discuss some possibilities. 

Some Thoughts from an Anthropologist on Culture, Interstellar Communication, and the Construction of Interstellar Messages

“Culture” represents one of the most widely used, but often misunderstood, concepts when considering the nature of interactions and communications between different, and mutually alien, groups. Dr. Traphagan will discuss ways of conceptualizing culture from an anthropological perspective and apply his approach to thinking about both the process interstellar message creation and the interpretation of any transmission we might receive.

The Allen Telescope Array: A Radio Survey Telescope for the 21st Century

Jill Tarter will talk about the large survey SETI observing programs to be undertaken by our in-house team over the next decade, the SETI observing projects from external proposers that have been allocated array time during this current observing period, some recently suggested 'far out' SETI observing strategies (not all relating to the ATA), our first thoughts about beginning OpenSETI, our recent successful demonstrations with SonATA0, and our plans for moving forward towards a Software Defined Radio Telescope (SDRT).

The Statistical Drake Equation

We provide the statistical generalization of the Drake equation.

SETI Institute - History, the Institute Today, and Plans for the Future

The Colloquium Series changes pace from our normal scientific discussions as SETI Institute CEO Tom Pierson invites everyone to join in a conversation. How did the Institute spring to life? What events punctuated its evolution? Why does the Institute have a Carl Sagan Center? What is the state of the Institute today? And what might the future bring?
