As per a new study, Dyson spheres around faint stars in the galaxy could offer new techno-signatures clues.

Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets ...

In Amiri’s calculations, Dyson spheres around white dwarfs tend to produce cooler, fainter thermal emission that peaks in the near- to mid-infrared, while M-dwarf cases can radiate more strongly but ...

I do so love an ostentatious comet. As I wrote in a recent “The Universe” column, when these dusty ice balls are billions of kilometers from the sun, they’re frozen solid. But as they near our star on ...

Recent research suggests that galaxies with high radio emissions—known as “radio-bright” galaxies—could be home to alien civilizations. This idea, explored in Brian C. Lacki’s study Artificial ...
