The ISS moves so fast it's only visible for one-third of a second
Amateur photographer Dylan O’Donnell has captured a stunning image of the International Space Station (ISS) flying by the Moon.
The photo, shared on Tuesday by the European Space Agency (ESA), was taken on June 30 with a Canon 70D camera placed behind a 2300 mm / f10 telescope, O’Donnell wrote on his website. The shutter speed was set at 1/1650th of a second, allowing him to capture the one-third second long moment during which the ISS — which orbits Earth at 28,000 km per hour (17,400 mph) — transits across the Moon.
“I take many types of pictures but the International Space Station is a wonderful target and one I’ve wanted to capture for a long time,” O’Donnell said in a statement.
