Quasars are actually a good example for length-contraction and curved
spacetime.
First we had to 'un-curve' the picture, to make it compatible to our
usual point of view here on Earth. The Earth orbit is a helix in the
spacetime-picture and we are kind of flowing with it, where the sun
defines an axis of our timelike path.
For a quasar we had to transform the picture observed (the pulsar) and
stretch space again and make the axis timelike. Than a pulsar would be a
usual binary star and a quasar a usual galaxy.
