A few days ago, a famous astronaut decided to take photos of Earth for 30 minutes. The resulting image is so surprising that we don’t even recognize our planet…
When you think of astronauts famous for capturing stunning images from space, the name NASA’s Don Pettit immediately comes to mind.
One of his photographs is notable for the presence of light trails, a technique in which all light sources appear as streaks of lines, generated by prolonged capture speed.

The image in question has several fascinating details, such as capturing a sunset and a sunrise simultaneously. In addition, circular star trails are visible above Earth and, zooming in on the lower part of the image, lightning and auroras can be seen.

The astronaut himself highlights several aspects of this image. For example, he specifies that the exposure is equivalent to a 30-minute capture during an orbital night and that it was taken with a new 15mm wide-angle lens, capable of covering a wider field of view.
