Large Magellanic Cloud Completes One Rotation Every 250M Years
2014-02-18 13:13:39

Scientists using the NASA Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years away from Earth.

Stellar Motions In Outer Halo Reveal Evidence Of Milky Way Evolution
