EXCELENTE este tema como siempre, hace rato no pasaba.
colaboro con un pequeño aporte.
These photos offer us a glimpse of Earth from the International Space Station.
As the ISS circles Earth at roughly 17,000 miles per hour, Flight Engineer Don Pettit takes 30-second exposures with a stock digital camera, then stacks those exposures into single frames that capture 10-15 minutes on the ISS.
The rotation is fast enough for long exposures to blur the earth into gilded landing strip beneath a steady rain of stars—a scene I would have never imagined as beautiful before today. Heck, it’s a scene I would have never even imagined before today.
