Hi,
The recent Astronomy Picture of the Day:
http://apod.nasa.gov/apod/ap111221.html
Has the following caption:
...the gravity of a luminous red galaxy (LRG) has gravitationally distorted the light from a much more distant blue galaxy.
I was under the impression that the more distant a galaxy is then the more red-shifted it becomes. So my question is how can the more distant galaxy be blue?
Thanks in advance.
