But during an eclipse, the Moon doesn\u2019t pass through the whole of the Earth\u2019s shadow. He needed a trick in order to show the whole thing.<\/p>\n<p>\u201cOne way, I thought, to get the full circle of the umbra from a single eclipse event is to artificially locate and rotate successive eclipse images so as the shadow boundary forms a circle,\u201d he said. \u201cThe trick is to keep the curvature of the shadow matching up as precisely as possible. Which images to choose is up to artistic license and I chose a spiral effect, not only to show the umbra but to also show the progression of the eclipse as time went on.\u201d<\/p>\n<p><!-- Link: <a href=\"https:\/\/gizmodo.com\/heres-what-earths-shadow-actually-looks-like-1828021990\">https:\/\/gizmodo.com\/heres-what-earths-shadow-actually-looks-like-1828021990<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The 21st century\u2019s longest lunar eclipse has passed, eclipse doomsday fever has subsided, and all that\u2019s left are the memories and pictures, which you can find everywhere online.
