Amazingly well-timed photos of ISS silhouetted against moon, sun
Both these remarkable shots were captured from the ground by French astrophotographer Thierry Legault.
The first, showing the ISS passing in front of the full moon, was taken from Avranches, France, at 21:34 UTC on December 20, 2010. The space station, of course, is much closer to the camera than the moon is, and is moving at 7.5 km/s relative to the ground, the upshot of which is that this photograph was only possible for the 0.55 seconds it took the ISS to pass in front of the moon. Monsieur Legault knew that, in advance, planned for it, and got the shot.
The second, even more remarkable photograph, shows a double partial eclipse of the sun, most obviously by the moon, to lower left, but also, again, by the ISS. The small dark spot to lower right is a sun spot larger than the Earth itself. This photograph was only possible for a 0.86 second window at 9:09 UTC on on January 4th, 2011, from Muscat, Oman. Again, Legault carefully planned for that moment, traveled to Oman, and got the shot.
M. Legault’s website is absolutely chock-a-block with stunning astrophotography and is well worth the click. Just be prepared to spend some time gawking. [via Neatorama]
