Attention, believers in extraterrestrial life! Exciting news has emerged from the scientific community, suggesting that potential evidence of alien structures around stars has been discovered. These colossal structures, known as Dyson spheres, could enable advanced alien civilizations to harness vast amounts of energy from stars.
Under Project Hephaistos, a team of astronomers from Uppsala University in Sweden and the International School for Advanced Studies in Italy embarked on a study using data from the ESA’s Gaia satellite, the 2MASS sky survey, and NASA’s Wise satellite. By analyzing data from these satellites, the researchers examined approximately five million stars and made a remarkable discovery.
Dr. Matías Suazo and his team at Uppsala University identified unusual signals emanating from seven red dwarfs within 900 light-years of Earth. These stars appeared to be around 60 times brighter in the infrared spectrum compared to normal stars, indicating the presence of something significant.
“These objects are all M-dwarfs, and astrophysical phenomena cannot easily explain the observed excess emission in the infrared,” the researchers explained. “This structure would emit waste heat in the form of mid-infrared radiation that, along with the level of completion of the structure, would depend on its effective temperature.”
The concept of Dyson spheres was first proposed by physicist Freeman Dyson in 1960. According to Dyson’s theory, an advanced civilization could construct a shell around a star to capture a substantial portion of its power. If the signals indeed originate from an extraterrestrial civilization, it is likely that they stem from a Dyson swarm—a group of large satellites encircling a star to harvest its energy.
Furthermore, the International School for Advanced Studies in Italy has identified 53 similar cases involving larger stars, including our own Sun, located up to 6,500 light-years away from Earth.
However, it is important to consider more conventional explanations for these infrared signatures. One possibility is that these stars are surrounded by hot debris resulting from planet formation, although the age of the stars raises doubts about this hypothesis.
“None of the proposed explanations clearly account for such a phenomenon in the candidates, particularly given that they are all M-dwarfs,” the researchers noted.
Another simpler theory posits that these stars may align with distant galaxies that emit the infrared glow.
In any case, the scientists involved in this research are eager to conduct further investigations and unravel the true nature of these intriguing phenomena. Who knows? They might even find evidence of alien life.
