Explanation: What's that unusual spot on the Moon? It's the International
Space Station [4] . Using precise timing, the Earth-orbiting space platform
[5] was photographed in front of a partially lit gibbous Moon [6]  last month.
The featured image was taken from Palo Alto [7] , California [8] , USA [9]
with an exposure time of only 1/667 of a second [10] . In contrast, the
duration of the transit of the ISS across the entire Moon [11]  was about half
a second [12] . A close inspection [13]  of this unusually crisp ISS
silhouette [14]  will reveal the outlines of numerous solar panels and
trusses. The bright crater Tycho [15]  is visible on the lower left, as well
as comparatively rough, light colored terrain known as highlands [16] , and
relatively smooth, dark colored areas known as maria [17] . On-line tools can
tell you when [18]  the International Space Station [19]  will be visible from
your area.
