COVER The Pleiades, also known as the Seven Sisters, is a cluster of stars easily seen in fall and winter that is critical for our understanding of stars throughout the universe. For decades, there has been considerable debate over the distance from our solar system to the Pleiades. Very long baseline radio interferometry now provides a "gold standard" distance measurement. See pages 1001 and 1029.
