Cute. This shot was taken at 1\/8000th of a second, which froze the action nicely.

You can clearly see the same sunspots, but the path of the spacecraft is slightly different, and the spots look a bit different as well. The equipment Heiko used was less fancy than what Thierry has, but you can still see a lot of detail in the image. It really is amazing that we can see such detail on the station from the ground!<\/p><p>I suspect the atmosphere was steadier at Thierry&rsquo;s observing site too; <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/www.astrophoto.fr\/iss_atlantis_transit2_2010.html\">in the images on his page<\/a> you can see the granulation on the surface of the Sun. Those granules are vast columns of hot gas rising to the Sun&rsquo;s surface, cooling off, then sinking again. It&rsquo;s a grand version of the convection that happens when you boil water in your teapot! <\/p><p><em>[Update: <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/www.perseus.gr\/Astro-Sat-Trans-2010-05-25.htm\">A third site with a great shot of the transit<\/a> was pointed out in the comments below. I wonder how many more are out there?] <\/em><\/p><p>These kinds of shots take a lot of planning, a lot of experience, and a bit of good fortune (or whatever politically correct term skeptics are supposed to use these days). When I was younger I shot a LOT of film of the Moon, and got maybe a 10% success rate if I was doing well. Digital cameras and the Internet make it a whole lot easier to get spectacular shots like these. I&rsquo;m glad to see more people tackling these difficult shots, and expect that we&rsquo;ll be seeing lots more like these as time goes on. <\/p><p><em>Tip o&rsquo; the dew cap to Thierry Legault and Jan Sorg for sending these to me.<\/em><\/p><p><a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/feedads.g.doubleclick.net\/~a\/N4imcuULXjX4CNvbg2npCEOa8aE\/0\/da\"><img decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/9d5cd_di\" border=\"0\" style=\"padding-left:10px; padding-right: 10px;\"><\/a><br><a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/feedads.g.doubleclick.net\/~a\/N4imcuULXjX4CNvbg2npCEOa8aE\/1\/da\"><img decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/9d5cd_di\" border=\"0\" style=\"padding-left:10px; padding-right: 10px;\"><\/a><\/p><p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/9d5cd_AWSvfWq7X-A\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/9d5cd_UH1r9THhinM\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><\/p>","protected":false},"excerpt":{"rendered":"<p>I have two more amazing images for you!
