A Dyson sphere is a hypothetical giant structure that surrounds a star and can capture its solar output. Two separate groups of astronomers have claimed that they have detected dozens of possible ...

The search for alien life takes many forms, from identifying Earth-like planets to scanning for extraterrestrial signals.

Seven different stars in our galaxy may show signs of being contained within Dyson spheres, megastructures that could be constructed by advanced civilizations to harness radiation energy from stars, ...

Two surveys of millions of stars in our galaxy have revealed mysterious spikes in infrared heat coming from dozens of them. Astronomers say this could be evidence for alien civilisations harnessing ...

Astronomers decided to look for partially constructed Dyson spheres and other megastructures around stars. They determined that half-built Dyson spheres or megastructures would be easy to see with our ...

Are there advanced alien “supercivilizations” lurking in our galaxy? If there are, they may use massive megastructures, such as a “Dyson sphere,” to harvest solar energy directly from a star. As first ...
