Oh, I see. Looks like they've corrected it.
On the Google website listing for the website I got it from after Googling "40,000 stars located within 326 light-years of our milky way" it says:
The Milky Way and beyond: Scientists publish new data ...
1 day ago — This image shows the paths of 40,000 stars located within 326 light-years of our Milky Way ...
but then on the website itself, it NOW says:
This image shows the paths of 40,000 stars located within 326 light-years of our solar system over the next 400,000 years based on measurements and projections from the European Space Agency's Gaia spacecraft.

So it looks like they've corrected it, the ponces.
