When people hear “Dyson sphere,” their first thought is probably a heavy-duty vacuum. They certainly don’t think of a megastructure surrounding and harnessing a star’s energy with the purpose of ...

If there are alien civilizations in the Universe, some of them could be super advanced. So advanced that they can rip apart planets and create vast shells surrounding a star to capture all its energy.

A group of researchers have identified at least seven stars that might be surrounded by advanced alien mega-structures known as "dyson spheres." NBC News' Ellison ...

Researchers found seven stars in our galaxy that might host alien megastructures called Dyson spheres. But these stars' strange behavior could also be explained by other phenomena, like clouds of dust ...

In the classic 1937 sci-fi novel "Star Maker," author Olaf Stapledon imagined a massive machine that could encompass an entire star, capturing its energy and harnessing it to provide near unlimited ...

(CNN) — What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or ...
