In quest to find alien life, scientists claim to have detected technological signatures from Dyson spheres


Space-enthusiasts looking for alien life may find a potential breakthrough in what some might call a futile mission.

Recently, some scientists have claimed to see technological signatures from Dyson spheres of a technological civilization.

The Dyson sphere is a hypothetical project whose ultimate aim is to capture the power of a star.

Many scientists are of the opinion that harnessing star energy is the only way to meet the energy needs of the far future.

However, this project is currently a dream for the people of this generation. It can be achieved only by remote civilizations that are highly advanced.

People of future civilization will have to build huge structures around the star to harness its power. Scientists believe that only those civilizations that measure Level II on the Kardashev scale can realize this dream.

In a brand new discovery, scientists from the US, UK, India and Sweden have developed a method to detect Dyson sphere signatures.

Named after the Greek god of fire and metallurgy, Project Hephaistos aims to search for life in outer space.

The Science Times The research team reported that the research team presented a comprehensive search for fractional Dyson spheres by analyzing infrared and optical observations from Gaia, WISE and 2MASS.

Led by lead author Matias Suazo, the paper is titled 'Project Hephaistos – II'. Dyson selected candidates from Gaia DR3, 2MASS, and WISE.

Gaia, 2MASS and WISE are astronomical surveys that generate large-scale data from individual stars.

“This second paper examines Gaia DR3, 2MASS, and WISE photometry of 5 million sources to catalog potential Dyson spheres,” the researchers said.

However, analyzing such extensive and large amounts of data is a difficult task. Thus, the researchers adopted a method in which they looked for partially filled areas that emitted additional infrared radiation.

But, the method also presents a hurdle. Dyson spheres are not the only ones that emit excess infrared radiation. Many natural celestial bodies do this too. (such as circumstellar dust rings and nebulae)

Thus, to cut through the chaos, scientists developed a special pipeline to detect anomalies. This pipeline focuses on sources that exhibit unusual infrared excess.

However even after the pipeline, the selected 'candidate' must pass a further test based on factors such as H-alpha emission, optical variability and astrometry.

“A special pipeline has been developed to identify potential Dyson sphere candidates, focusing on detecting sources that exhibit unusual infrared excesses that cannot be detected by any known natural source of such radiation,” the researchers explained. “Can't be held responsible for.”
