In evaluating the number of technological civilizations N in the Galaxy through the Drake formula, emphasis is mostly put on the astrophysical and biotechnological factors describing the emergence of a civilization and much less on its the lifetime, which is intimately related to its demise.

Are advanced civilizations in our galaxy trying to communicate with us by means of laser blasts? A team of University of California, San Diego, UC Berkeley, Harvard University and California Institute of Technology astronomers are building a pair of fly's-eye observatories to find out.

The steady advances in computer performance and in programming raise the concern that the ability of computers would overtake that of the human brain, an occurrence termed "the Singularity".

Data from a massive search for cosmic radio emission released Feb 14. by the Breakthrough Listen Initiative--the most comprehensive survey yet of radio emissions from the Milky Way--has allowed astronomers to look for technological signatures of extraterrestrial civilizations that might be looking for us.

We report on a search for artificial narrowband signals of 20 stars within the restricted Earth Transit Zone as a part of the ten-year Breakthrough Listen (BL) search for extraterrestrial intelligence.

Emerging technologies and new strategies are opening a revitalized era in the search for extraterrestrial intelligence (SETI).

The Breakthrough Listen Initiative today (Friday, Feb. 14) released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations.

The Search for Extraterrestrial Intelligence (SETI) attempts to address the possibility of the presence of technological civilizations beyond the Earth.

Low mass X-ray binaries (LMXBs) containing neutron stars are both extremely luminous and compact, emitting up to ~10^6 L_sun within a kilometer-scale boundary layer. This combination allows for easy modulation, motivating X-ray SETI.

An artificial neural network has identified a square structure within a triangular one in a crater on the dwarf planet Ceres, with several people agreeing on this perception.

Searching For A Standard Drake Equation

In the 20th century the scientific search for extraterrestrial intelligence began, and the Drake equation was proposed to estimate the number of extraterrestrial species humanity could attempt to detect, N.

The star EPIC 249706694 (HD 139139) was found to exhibit 28 transit-like events over an 87 day period during the Kepler mission's K2 Campaign 15 (Rappaport et al. 2019).

A radio transmitter which is accelerating with a non-zero radial component with respect to a receiver will produce a signal that appears to change its frequency over time. This effect, commonly produced in astrophysical situations where orbital and rotational motions are ubiquitous, is called a drift rate.

We analyze the potential transit light curve effects due to a Clarke belt of satellites around an exoplanet.

Looking for Lurkers: A New Way to Do SETI

The most recently discovered group of rocky bodies nearby Earth are termed co-orbital objects. An attractive location for extraterrestrial intelligence (ETI) to locate a probe to observe Earth throughout our deep past are the co-orbital objects.

Allen Telescope Array Upgrade Program Funded

The SETI Institute announced a new gift by Qualcomm founder Franklin Antonio that funds the first phase of a 3-year initiative to revitalize the Allen Telescope Array (ATA).

We present modeled detection limits of the Gemini Planet Imager (GPI) and the Wide-Field Infrared Space Telescope (WFIRST) to an optical and infrared laser which could be used by an extraterrestrial civilization to signal their presence.

In this work, we motivate, describe, and announce a living bibliography for academic papers and other works published in the Search for Extraterrestrial Intelligence (SETI).

The discovery of the ubiquity of habitable extrasolar planets, combined with revolutionary advances in instrumentation and observational capabilities, have ushered in a renaissance in the millenia-old quest to answer our most profound question about the Universe and our place within it - Are we alone?

Traditional searches for extraterrestrial intelligence (SETI) or "technosignatures" focus on dedicated observations of single stars or regions in the sky to detect excess or transient emission from intelligent sources.
