The Radcliffe Wave is Oscillating. (https://pubmed.ncbi.nlm.nih.gov/38378142/)

These scientists studied a long, wavy chain of dense gas clouds called the Radcliffe Wave that is close to our Sun in space. They used special techniques to map out the shape of this wave and found that it looks like it's moving in a wave-like motion through our galaxy. They also discovered that it is drifting away from the center of our galaxy.

To figure this out, the scientists looked at how fast the gas clouds in the Radcliffe Wave were moving towards or away from us, as well as how fast young star clusters associated with the wave were moving in different directions. By studying these movements, they were able to show that the Radcliffe Wave is like a big wave that is being pushed and pulled by the gravity of our galaxy.

This study helped the scientists learn more about how our galaxy is structured and how different parts of it are moving. They also found clues about the birth of a cluster of stars that eventually led to the creation of the expanding Local Bubble in space.
