For the first time, astronomers have detected Cepheids in the Sculptor group
galaxy NGC 55 and used these cosmic yardsticks to measure its distance. That
distance matches the distance of the spiral galaxy NGC 300, suggesting the
two galaxies may orbit each other. For the full story, including a color
image of NGC 55, please see http://KenCroswell.com/NGC55Cepheids.html .
Note: The Sculptor group is the nearest galaxy group to the Local Group.
