A giant stars wave Extending from the center of the galaxy outward, the Gaia Space Telescope is identified, according to a statement from the European Space Agency (ESA).

The stars of our galaxy revolve around its center, while the Gaia telescope has accurately recorded their speeds and movements. In addition, it was found that the galaxy disc shows oscillations over time, similar to the movement of a spin.

The Gaia Space Telescope, which stopped operating last March, has offered the largest and most accurate multi -dimensional map of our galaxy. The analysis of his data revealed a large wave, which moves stars at distances of tens of thousands of light -years from the sun. ESA resembles the phenomenon to the ripples created by a stone when it falls into the water.

According to scientists, this wave extends to much of the galactic disc, affecting stars 30 to 65 thousand light -years from the center of the galaxy.

This move was identified by studying the positions and movements of young giant stars and Kifidis, a group of variable stars that are important indicators to measure galactic and extra -distances. Scientists estimate that gas on the galaxy disc may also be involved in this wavy flow.

The origin of these galactic vibrations remains unknown. A possible explanation is an earlier conflict with a dwarf galaxy, but this possibility requires further investigation. The wave may also be associated with the smaller -scale corrugated movement observed at a distance of 500 light -years from the sun, known as Rascale wavein a different area of ​​the galactic disc.

The research was published in the magazine Astronomy and Astrophysics.
