Crescent Mercury in Color
Explanation: Hard to spot against the
twilight glow
near planet Earth's horizon, a crescent Mercury was imaged close up by the
MESSENGER
spacecraft early last week. Colors in this
remarkable picture
were created using data recorded through infrared, red, and violet filters. The combination enhances color differences otherwise not visible to the eye across the innermost planet's
cratered surface
. In this view,
light bluish
material seems to surround relatively new craters,
contrasting
with the mostly drab, brown terrain.
Mercury itself is 4,880 kilometers in diameter. The full resolution image shows features as small as 10 kilometers across.
