The twenty-first one C ’s longest lunar eclipse has buy the farm , eclipse doomsday fever has subsided , and all that ’s left are the memories and pictures , which you’re able to retrieve everywhere online . But one epitome really stood out to us — not because of the room the Moon look , but because of how it made the Earth feel .
Australian amateur astronomerTom Harradinehad always need to create an image of the Earth ’s umbra , the blue inner region of the shadow . But during an occultation , the Moon does n’t pass through the whole of the Earth ’s shadow . He needed a legerdemain so as to show the whole affair .
“ One way , I thought , to get the full circle of the umbra from a single eclipse event is to by artificial means site and rotate successive eclipse images so as the shadow bound forms a rophy , ” he articulate . “ The whoremonger is to keep the curvature of the shadow matching up as precisely as possible . Which images to prefer is up to artistic license and I chose a spiral issue , not only to show the umbra but to also show the progression of the eclipse as time give-up the ghost on . ”
The upshot was this image , the combination of some photo arranging and special camera tricks : keeping the photographic camera ’s picture , ISO , and f - contain configurations the same for all but the first three frames of the eclipse ( the brightest ones ) to focus on the darkness , not the Moon . He used his image to correctly cypher the width of the Earth ’s umbra at the Moon ’s distance , just about 9,000 kilometer or 5,590 miles .
Though it was clouded the midnight prior , when he woke up at 3:30 a.m Brisbane metre on Saturday , July 28 , the sky was totally clear . He rushed to set up his Dobsonian telescope . Brisbane , Australia caught the occultation at dawn , but Harradine needed only to photograph one-half of the eclipse to create the image . He was also able towatch the International Space Stationpass through the Earth ’s shadow at 5:35 a.m. , and took some awesomepictures of Marsyesterday .
“ It was amazing to see the ISS emerge from the very same … apparition that was eclipse the Moon , ” he told Gizmodo . The shadow takes up a different amount of blank in the sky proportional to the ISS than for the Moon , since the ISS is around a thousand times closer .
