Milky Way Mapping Project Finds Surprisingly Slow Stars

This map of the near side of the Milky Way, a combination of an artist's conception and real data points, shows several spiral arms. The sun (red circle) is located on a spur between two of the arms. Blue circles mark star-forming regions whose distances have been accurately measured using parallax. Credit: Bill Saxton (NRAO) and Mark Reid (CfA)
