From JPL comes this view of Earth from afar:

This composite image of Earth and its moon, as seen from Mars, combines the best Earth image with the best moon image from four sets of images acquired on Nov. 20, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

Each was separately processed prior to combining them so that the moon is bright enough to see. The moon is much darker than Earth and would barely be visible at the same brightness scale as Earth. The combined view retains the correct sizes and positions of the two bodies relative to each other.

HiRISE takes images in three wavelength bands: infrared, red, and blue-green. These are displayed here as red, green, and blue, respectively. This is similar to Landsat images in which vegetation appears red. The reddish feature in the middle of the Earth image is Australia. Southeast Asia appears as the reddish area (due to vegetation) near the top; Antarctica is the bright blob at bottom-left. Other bright areas are clouds.

Composite image?! It's NASA trickery!

Also at Space.com. Compare with the Pale Blue Dot and The Day the Earth Smiled.

    uhm... so what's the problem? are you saying we shouldn't look at Saturn's rings from Earth, because it looks like part of them is actually ON Saturn? or maybe we should never take pictures of Jupiter's moons when they are almost eclipsed by it.

    They specifically said that the position, size and orientation are unaltered; the only things modified where brightness of moon relative to Earth, and picking, for each one, the best out of 4 snapshots taken at a short time from one another.
    Basically, if you looked through a telescope from Mars on the same date you would see more or less the same thing (depending on how well your eye can adapt to the brightness of the Earth).
