Lauren Harnett, a NASA photographer captured images of the moon at the exact moment that the space station passed across its face, what scientists call a "transit."
The photos were taken on Wednesday (Jan. 4) from the Johnson Space Center in Houston.

The International Space Station is the largest spacecraft ever built, longer than a football field.

At its brightest, the space station can outshine the planet Venus and be easily spotted with the unaided eye by skywatchers who know where to look.

"The space station can be seen in the night sky with the naked eye, and a pair of field binoculars may reveal some detail of the structural shape of the spacecraft," NASA officials explained in an image description.

In the photos, the moon appears inclear detail, and the shape of the space station's huge solar arrays and backbone can be recognized.
