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 ...

Ever since physicist Freeman Dyson first proposed the concept in 1960, the "Dyson sphere" has been the holy grail of ...

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 ...

Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

The first bubble of hot gas seen around another star has been spotted around the "Moth," just 117 light-years away.

An artist’s impression of exocomets orbiting the star Beta Pictoris. I do so love an ostentatious comet. As I wrote in a recent “The Universe” column, when these dusty ice balls are billions of ...
