About this Image

Background infrared image of part of the Cepheus A star-forming region, with magnified inserts. The insert in the middle is a radio image, with water masers marked as crosses. The insert at the bottom right is an enlargement of one of these regions, as observed with the VLBA. This enlargement shows that the water masers form an arc which fits a circle to within one part in a thousand.
