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 ...

A team of astronomers combed through a collection of odd stars that are candidates for Dyson spheres — artificial constructs designed by aliens to leech energy from stars. Instead, the scientists ...

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 ...

There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts ...

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 ...
