Hitting the Books: We'd likely have to liquidate Jupiter to build a Dyson Sphere around the Sun. But it could be the beacon we need to finally attract extra-terrestrial attention.

We'd need an astronomical amount of resources to construct a Dyson sphere around the Sun, ... and not just a small one — more like Jupiter," Green writes in her book.

For over 60 years, one intriguing concept in this search is the idea of a Dyson Sphere. ... Dyson Spheres have become a ...

That’s too bad. If it could be stabilized, a Dyson Sphere built at 93 million miles from the sun, the same distance as Earth, would contain about 600 million times the surface area of our planet ...

Proposed by physicist Freeman Dyson in 1960, a Dyson Sphere represents a theoretical megastructure that could ... books, and ...

Instead, Dyson clarified his original paper by saying that a swarm of small solar-energy collectors all around a star would be more viable than a giant, solid sphere, since even if one part of the ...

For these and many other reasons, a Dyson sphere costs energy. So we’re going to see how long it will take to recoup the energy investment of building one and what the optimal design might be to ...

This image shows what a Dyson sphere could look like. Signs of these energy-collecting megastructures may have been detected around seven stars.

It doesn’t have to be a sphere per se; the proposals often see it as a swarm of solar panels harvesting and then transferring said energy to hubs or planets. Those are specifically called Dyson ...
