A View of Earth and the Moon from Mars.

Photographic Image by NASA/JPL-Caltech/Univ. of Arizona
During a recent calibration exercise, NASA’s Mars Reconnaissance Orbiter captured a remarkable view of Earth and its moon from a distance of 127 million miles (205 million kilometers).
It’s so clear, you can even make out our planet’s continents.
To calibrate the HiRISE camera aboard the Mars Orbiter, NASA scientists needed to scan an object other than the Red Planet.
Seeing as Earth is right next door, that was an obvious choice.
The image is a combination of two separate exposures taken on November 20, 2016, and have been moderately adjusted to make both objects appear equally as bright (otherwise the Earth would have appeared too dark).
The combined view shows the correct positions and sizes of the two celestial bodies relative to each other.

“This is a composite image consisting of 150 images to create the star-trails, one image for the truck ‘moving’ head and tail lights, and one for the foreground.
All images were taken on the same night just outside the city limits of Bourke, New South Wales, Australia, and took several hours to make.”
