Broken spheres
Dyson died in 2020 before any of his spheres could be found although they are just one of a dozen ideas that bear his name.

“As a young scientist, Dyson showed that three competing quantum theories were actually the same theory he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.”
George Dyson also attested to his father’s fascination and comprehensive reach across disciplines.

“Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’”
The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study.
“However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.” |

Possibilities
The authors of the study, published May 6 in the journal Monthly Notices of the Royal Astronomical Society, specifically set out to search for Dyson spheres, in the form of infrared heat near stars that couldn’t be explained in any other way.

Using historical data from telescopes that pick up infrared signatures, the research team looked at stars located within less than 1,000 light-years from Earth: “We started with a sample of 5 million stars, and we applied filters to try to get rid of as much data contamination as possible,” said lead study author Matias Suazo, a doctoral student in the department of physics and astronomy of Uppsala University in Sweden.
“So far, we have seven sources that we know are glowing in the infrared but we don’t know why, so they stand out.”

There is no conclusive evidence that the seven stars have Dyson spheres around them, Suazo cautioned.
“It’s difficult for us to find an explanation for these sources, because we don’t have enough data to prove what is the real cause of the infrared glow,” he said. “They could be Dyson spheres, because they behave like our models predict, but they could be something else as well.”
Among the natural causes that could explain the infrared glow are an unlucky alignment in the observation, with a galaxy in the background overlapping with the star, planetary collisions creating debris, or the fact that the stars may be young and therefore still surrounded by disks of hot debris from which planets would later form.
The data used by the researchers comes from two active space telescopes the Wide-field Infrared Survey Explorer, or WISE, from NASA and Gaia from the European Space Agency as well as an astronomical survey of the sky in infrared light called The Two Micron All Sky Survey. Also known as 2MASS, the collaboration between the University of Massachusetts and the US space agency’s Jet Propulsion Laboratory took place between 1997 and 2001. |
