    Scientists using NASA’s Hubble Space Telescope found that the Large Magellanic Cloud completes a rotation every 250 million years.  They measured the average motion of hundreds of individuals stars in the galaxy located 170,000 light-years from Earth to arrive at this conclusion.  But why does it even matter?   Well, according to scientists, knowing a galaxy’s rotation rate offers insight into how a galaxy formed, and can be used to calculate its mass.”  And it might provide a little insight into our own Milky Way as it’s the closest to us.  It’s hard to study the Milky Way since we’re looking from the inside-out but maybe looking at the LMC from the outside-in will help us learn more about our home galaxy.
