I'm not sure if this is the right place to post this, but I thought it might be of interest ...

Thanks for posting. Could be because of the projection, but the animation of the nearby star motions is far more chaotic than what I would have imagined. Seems to be a lot of stars heading in opposite directions, at least relative to us. ... I guess thats it - it's all relative velocities, we're all still moving together around the galaxy.

 

Also interesting to see how quickly our local neighbourhood spreads out - puts any search for our sibling stars into context

That's very interesting. It points out how massive the distances are when stars we see seem to be in the same position night after night.

There is a fascinating Twitter account called Milky Way Astronomers @MAstronomers that I follow.

On 02 Dec 20 they posted this incredible photograph entitled 'Storm under the Milky Way' which is almost 3D.

I do not know who the photographer is, nor how it was produced (Photoshop, etc) but all credit goes to them.
