If there are any Dyson spheres, rings, or swarms out there, the person or research team that finds them will go down in history as one of the most significant discoveries in the history of astronomy.
Dyson spheres are artificial spheres around a star. If they are ever constructed, they are more likely to appear as a partially completed sphere, or even a ring, of small habitats that encompass their host star.
The focus of the work by Dr. Zuckerman is scanning different white dwarfs for anomalies that might indicate an artificial construct surrounds them.
We are currently in the main sequence of the life cycle of a solar mass object, which leads to a red giant phase in which many of the planets have accumulated.
While white dwarfs are still alive, they emit thermal radiation that can be absorbed and reappropriated to power a DSR.
Zuckerman's previous work points to the possibility that some of the technologically advanced civilizations in the Milky Way would have experienced their host star turning into a white dwarf.
There have been observational campaigns at both WISE and Spitzer. The researchers thought dust was the most likely cause of the anomalies, and there was no evidence of a DSR.
The absence of evidence is not evidence of absence, but it does help to constrain the likelihood.
Science continues to collect data that will either further constrain the estimates of the number of advanced technological civilizations in our galaxy or prove that we are not alone once and for all.
