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 ...

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, ...

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

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 ...

The Dyson Sphere concept is a staple of science fiction, from Star Trek to the novels of Larry Niven, and it sounds like a dream come true: a way to harvest almost all of the immense energy output of ...

We may receive a commission on purchases made from links. All of our planet's energy — whether it's gained from food, fossil fuels, or renewable sources — ultimately comes from the sun. Solar ...

In 1960, British theoretical physicist Freeman Dyson published a one-page paper in the journal Science that offered perhaps the most hopeful vision ever conceived of humanity’s technological future.

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 ...

In 1960, visionary physicist Freeman Dyson proposed that an advanced alien civilization would someday quit fooling around with kindergarten-level stuff like wind turbines and nuclear reactors and ...

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 ...
