The Gaia Space Telescope of the European Space Agency discovered a young star family in our galaxy that exhibited unusual behaviors. This group, called “Ophion, consists of more than 1,000 stars and tends to disperse in a much shorter time than its similar.
The stars in the Milky Way are usually born in clusters and gradually separated from each other and dispersed into the galaxy. However, the Ophion stars are unusual and quickly distant from each other. Dylan Huson, the editor -in -chief of the study, said, ında It is unusual to disintegrate such a large group at this speed, ”he said.
Researchers have developed a new artificial intelligence model to analyze hundreds of millions of star spectrums in Gaia’s third data broadcast. Thanks to this model, the stars of 20 million years were scanned and Ophion appeared. This success is one of the first studies in which the data of young stars can be analyzed massively.
Supernova or a neighbor effect?
According to Scitech Daily; There are other major star groups near Ophion, and it is thought that Supernova explosions may have happened here in the past. Such explosions may have broken the orbits of the stars by sweeping the substances in the region where the stars are located.
Researchers have not found a clear reason to fully explain Ophion’s behavior. However, this discovery shows that the traditional methods used to identify star groups may be insufficient. Gaia’s giant data archive and new analysis techniques reveal the dynamics that have not been noticed before.
The Gaia satellite, whose observations ended in 2024, left behind a huge data treasure. At the end of 2026, a new data set will be shared with the public “Heritage Data” after 2030. Scientists expect numerous discoveries from these data in the coming years.
