In the modern search for life elsewhere in the Universe, we are broadly looking for the following: the planets similar to Earth – physical indicators of habitability, and the manifestation […]

Monte Carlo Estimation Of The Probability Of Causal Contacts Between Communicating Civilisations
In this work we address the problem of estimating the probabilities of causal contacts between civilisations in the Galaxy. We make no assumptions regarding the origin and evolution of intelligent […]
Investigating The Possibility Of Life Below The Surface Of Mars
Although no life has been detected on the Martian surface, a new study from astrophysicist and research scientist at the Center for Space Science at NYU Abu Dhabi, Dimitra Atri […]
Reworking the SETI Paradox: METI's Place on the Continuum of Astrobiological Signaling
The Search for Extraterrestrial Intelligence (SETI) has heretofore been a largely passive exercise, reliant on the pursuit of technosignatures. Still, there are those that advocate a more active approach. Messaging […]
Qualitative Classification of Extraterrestrial Civilizations
Abridged: The interest towards searches for extraterrestrial civilizations (ETCs) was boosted by the discovery of thousands of exoplanets. We turn to the classification of ETCs for new considerations that may […]
Habitability Is A Continuous Property Of Nature
In their recent comment, Cockell et al. argue that the habitability of an environment is fundamentally a binary property; that is to say, an environment can either support the metabolic […]
A Probabilistic Analysis Of The Fermi Paradox In Terms Of The Drake Formula: The Role Of The L Factor
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 […]
Will Recent Advances In AI Result In A Paradigm Shift In Astrobiology And SETI?
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”. While […]
There's No Place Like Home (in Our Own Solar System): Searching for ET Near White Dwarfs
The preponderance of white dwarfs in the Milky Way were formed from the remnants of stars of the same or somewhat higher mass as the Sun, i.e., from G-stars. We […]
Exoplanets Can Be Made Less Habitable By Stars' Flares
The discovery of terrestrial exoplanets, planets that orbit stars outside the solar system, has been one of the most significant developments in modern astronomy. Several exoplanets lie in the “habitable […]
