Astronauts aboard the International Space Station are taking sightseeing to new heights.
In the video above, viewers are invited to join Expedition 38 crew members Mike Hopkins and Rick Mastracchio as they pick out various cities on the planet's slowly spinning surface.
The footage was taken from the station's Cupola, a multi-windowed observation module that's a favorite spot for astronauts.
In this image provided by NASA, astronauts Mike Kelly, left, and Ron Garan get their picture taken in the Cupola by astronaut Mike Fincke while he floats outside the International Space Station on Thursday May 26, 2011.
Can you pick out the cities before the astronauts do? Watch the video to find out -- and enjoy a geography lesson that's literally out of this world.
