You really need to get some image manipulation software like Paint Shop Pro and crop part of the image and highlight it. I can't see what you are alluding to.
And to ArmchairObserver - before you come to any conclusions about life on Mars, bear in mind it is a pretty hostile, dry and arid place not capable of supporting any form of life and with average temperatures down to -60 deg C. It has an atmosphere mainly consisting of Carbon Dioxide, an atmosperic pressure 100 times thinner than that on earth and consequently high levels of sterilising radiation from the sun reach the surface. Water cannot maintain itself in stable form either due to the Triple Point effect. You took all this into account, didn't you?
