Large Magellanic Cloud Rotation Cycle
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.
