A mysterious movement has been observed at the heart of our galaxy

Our galaxy, also known as the Milky Way, is not static in space, as it spins like a top, deforming its arms. But recently, observations from the Gaia space telescope have revealed a mysterious phenomenon within our galaxy, whose origin remains unknown.

This phenomenon was highlighted in a study published in the journal Astronomy and Astrophysics. More specifically, it appears to be a gigantic wave spreading throughout the entire galaxy, altering the movement of the stars located there.

To better understand this phenomenon, we can refer to several images. The image on the left shows our galaxy from above, and the one on the right shows a side view. Note that the wave is represented by the colors red and blue, and in the red areas, the stars are above the galactic disk, while in the blue areas, they are located below it.

A second image provides a better understanding of the consequences of this wave. In this image, the arrows indicate the movements of the stars, with variations depending on the areas affected.

However, no formal evidence has yet been found regarding the origin of this gigantic wave. It must be said that this discovery is recent and many studies and observations still need to be carried to unravel this mystery. But some hypotheses have already been put forward, such as a collision with a dwarf galaxy several billion years ago, which could explain this phenomenon.
