The chances of intelligent life emerging in our Universe – and in any hypothetical ones beyond it – can be estimated by a new theoretical model which has echoes of […]
The search for extraterrestrial intelligence is a fascinating and important endeavor, but it raises significant ethical and safety concerns. In the search for extraterrestrial intelligence, scientists use knowledge of physics […]
A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, […]
The quest for radio signals from technologically-advanced extraterrestrial intelligence has traditionally concentrated on the vicinity of 1.4 GHz.
Soon after the release of the WISE all-sky catalogue of 500 million mid-infrared (IR) objects, suggestions were made that it could be used to search for extrasolar devices constructed by […]
University of Southampton scientists have stored the full human genome on a 5D memory crystal – a revolutionary data storage format that can survive for billions of years. The team […]
![Quantum communication with Q > 0, over distance L, is impossible at wavelengths where the horizontal line corresponding to L lies within the blue shaded region (summarizing the Milky Way ISM’s extinction curve). Gray regions are off limits from the ground.

Since it began Cocconi Morrison, the search for extraterrestrial intelligence (SETI) has focused on interstellar classical communication. Recently, Berera:2020rpl pointed out that, at certain frequencies, photon qubits can retain their […]
Planet-planet occultations (PPOs) occur when one exoplanet occults another exoplanet in the same system as seen from the Earth’s vantage point. PPOs may provide a unique opportunity to observe radio […]
This study uses methods from futures studies to develop a set of ten self-consistent scenarios for Earth’s 1,000-year future, which can serve as examples for defining technosignature search strategies.
While there exist more contentious geochemical and molecular clock estimates for these steps that would place them each farther back in time, we have chosen the least controversial evidence to […]
