Expedition 35 commander Chris Hadfield shared a photo on a social networking site, showing a portion of one of the solar array wings on the ISS with a small but very visible hole made by a passing meteoroid.
Hadfield referred to the object in one of the panel cells as "a small stone from the universe."
"Glad it missed the hull," Hadfield said.
Likened to a bullet hole, whatever struck the solar panel was actually travelling much faster when it hit, 'Universe Today' website reported.
The ISS, luckily, has a multi-layered hull consisting of layers of different materials, providing protection from micrometeorite impacts.
If an object were to hit an inhabited section of the Station, it would be slowed down enough by the different layers to either not make it to the main hull or else merely create an audible "ping.
