Seven candidate stars identified to “host” the presence of Dyson spheres. The study of astronomers

In the boundless space of our galaxy there would be at least seven stars which show signs attributable to Dyson spheres. These, according to scientists, are hypothetical constructions created by civilization equipped with technological skills advanced to harness the energy of their stars or surrounding black holes. The discovery has attracted the attention of those engaged in the search for extraterrestrial life and also of those who are passionate about it.

In the research sector it is believed that Dyson spheres are interceptable thanks to the large quantities of infrared radiation emitted by them in the process of extracting energy from the stars. Therefore, in tracking them one of the most used methods is hunting peaks in these wavelengths, known as excess infrared emissions (IEE).

The researchers behind the study leveraged a computer program to look for these emissions in over 5 million of stars in our galaxy, examined by observatories such as satellite Gaia of the European Space Agency and the Wide-field Infrared Survey Explorer (WISE) from NASA. And the program responded by finding seven candidate stars to host Dyson spheres, behind which advanced civilizations could therefore hide. However, as he explains Focusexcess infrared may result from other factors: “The presence of records of hot debrisfor example, surrounding our candidate stars remains a valid explanation.”

The discovery was published on May 6th in the scientific journal Monthly Notices of the Royal Astronomical Society. The concept of the Dyson sphere first appeared in 1960 and was theorized by the physicist, who died in 2020 at the age of 96, Freeman John Dyson. The general idea behind it claims, in fact, that a technologically advanced alien civilization would be able to build enormous structures around their stars to draw energy from them. The most extreme version of these structures would see a sphere enclosing an entire star.
