We report radio SETI observations on a large number of known exoplanets and other nearby star systems using the Allen Telescope Array (ATA) for about 19000 hours from May 2009 […]

The SERENDIP III 70 cm Search for Extraterrestrial Intelligence
We employed the SERENDIP III system with the Arecibo radio telescope to search for possible artificial extraterrestrial signals. Over the four years of this search we covered 93% of the […]

The Search for Extraterrestrial Intelligence in Earth's Solar Transit Zone
Over the past few years, astronomers have detected thousands of planets and planet candidates by observing their periodic transits in front of their host stars. A related transit method, called […]

A Search for Brief Optical Flashes Associated with the SETI Target KIC 846285
The F-type star KIC~8462852 has recently been identified as an exceptional target for SETI (search for extraterrestrial intelligence) observations. We describe an analysis methodology for optical SETI, which we have […]

The Aliens Are Silent Because They Are Extinct
Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU). In research aiming to understand how life might develop, […]

Globular Clusters Could Nurture Interstellar Civilizations
“A globular cluster might be the first place in which intelligent life is identified in our galaxy,” says lead author Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics (CfA). […]

Conformal Cyclic Cosmology and the Fermi Paradox
Within the scheme of conformal cyclic cosmology (CCC), information can be transmitted from aeon to aeon. Accordingly, the “Fermi paradox” and the SETI programme – of communication by remote civilizations […]

Advanced Alien Civilisations Rare or Absent in the Local Universe?
Sensitive new telescopes now permit astronomers to detect the waste heat that is expected to be a signature of advanced alien civilisations that can harness enormous energies on the scale […]

Observational Signatures of Self-Destructive Civilizations
We address the possibility that intelligent civilisations that destroy themselves could present signatures observable by humanity. Placing limits on the number of self-destroyed civilisations in the Milky Way has strong […]
