A spaceship is traveling at 0.89c relative to a spiral galaxy. The pilot, in an attempt to measure the size of the galaxy, determines the length of the long axis of the galaxy (the widest part of the galaxy) to be 2.5 × 104 parsecs. What would the length of this axis be as measured by a nearby alien observer at rest relative to the galaxy in parsecs?
