TORONTO – While Saturn may be getting all the attention for photographing Earth, Mercury was doing its own bit of photography on Friday.
NASA’s Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) spacecraft, which is currently orbiting Mercury, turned its own cameras toward Earth, capturing our planet and the moon in a photograph.
MESSENGER took the photograph while searching for moons of Mercury. Because Mercury itself is so small, any moons that would be around the planet would be much smaller, so MESSENGER’s cameras had to overexpose the images. This is why Earth and the moon seem very large and bright in this image.
MESSENGER was 98 million km from Earth when the photo was taken.
