Proper motion of stars outside Milky Way

I cut this clipping out from Science Daily..
It seems rather exciting on a number of levels...

I am pressed for time and will get back with a link....

From Astronomy Daily and all credit to them...their article says...
First proper motions measured of stars in a small galaxy outside the Milky Way
Findings question models of dark matter halos
Date:
November 27, 2017
Source:
University of Groningen
Summary:
By combining data from the Hubble Space Telescope and the Gaia mission, astronomers have been able to measure the proper motion of 15 stars in the Sculptor Galaxy, the first such measurement outside the Milky Way. Analysis shows an unexpected preference in the direction of movement, which suggests that the standard theoretical models used to describe the motion of stars and dark matter halos in other galaxies might be invalid.

End.

That's part of it but I will get back to it..must go
