![Images in the JWST/MIRI F560W, F1000W and F1500W filters (central wavelength ≈ 5.6, 10 and 15 𝜇m) of candidates D (first row) and E (second row). White stars mark the Gaia positions of the M dwarfs, which in both cases are seen to be located ≈ 1 arcsec from the centres of background galaxies. -- [astro-ph.GA]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/Project-Hephaistos.png?resize=1200%2C720&ssl=1)
[astro-ph.GA] We report on JWST/MIRI imaging and spectroscopy of two M-dwarf stars previously singled out by project Hephaistos as potential Dyson-sphere candidates (their candidates D and E) due to the […]

Making Habitable Worlds: Planets Versus Megastructures
In 2016, a star KIC 8462852 caught the world’s attention due to a paper by citizen scientists who noticed its seemingly unexplainable brightness variations. The forward theory was offered – […]

Technosignatures: Did WISE Detect Dyson Spheres/Structures Around Gaia-2MASS-selected Stars?
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 […]
