This paper presents a classification framework for the architectures of planetary systems based on a complete survey of the confirmed exoplanet population.
In his 1856 Adams Prize essay, James Clark Maxwell demonstrated that Saturn’s rings cannot be comprised of a uniform rigid body. This is a consequence of the two-body gravitational interaction […]
Astronomy, of all the sciences, is possibly the one with the most public appeal across all age groups. This is also evidenced by the existence of a large number of […]
We present high-resolution e-MERLIN and EVN (e-VLBI) observations of a radio source associated with Dyson Sphere candidate G, identified as part of Project Hephaistos.
Editor’s note: If you search for a definition for tricorder you’ll find things like this from Wikipedia: “A tricorder is a fictional handheld sensor that exists in the Star Trek […]
![[L] The x-axis is the Sagan’s parameter of the Kardashev civilization Type K. The y-axis is the mass of PBH in solar mass for a fraction fPBH = 0.01. The colour-bar of the contours shows the quantity Kachieved/K − 1, which Kachieved is the amount of civilization parameter achieved by PBHs. [R] The x-axis is the Sagan’s parameter of the Kardashev civilization type. The y-axis is the fraction of PBH for a mass of MPBH = 1M⊙.

Are we alone? It is a compelling question that human beings have confronted for centuries. The search for extraterrestrial life is a broad range of quests for finding the simple […]
This study uses methods from futures studies to develop a set of ten self-consistent scenarios for Earth’s 1000-year future, which can serve as examples for defining technosignature search strategies.
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 […]
We present a novel approach for identifying cosmic web filaments within the DisPerSE structure identification framework, using cosmic density field estimates from the Monte Carlo Physarum Machine (MCPM), inspired by […]
