Fun fact to hold you over while you queue up the talk: The International Space Station has the same interior volume as two Boeing 747 jets, and can travel the distance between Paris and New York in 12 minutes.

Starlight + long exposure + the International Space Station = totally rad

TEDxHouston speaker Don Pettit’s photos from the ISS might have your Instagram feed beat. The cosmonaut’s beautiful images — seen above — capture the trails of light created by stars over a period of 10-15 minutes in captivating detail.

When down on Earth, the NASA flight engineer gave a talk on the fascinating physics of space travel, which we promise isn’t as daunting as it sounds.
