Ever wonder how NASA takes images from satellites in orbit and recreates the Earth from those images? NASA has posted an article highlighting Helen-Nicole Kostis, shown in the above image, who is a NASA scientific visualizer. It is her job to combine hundreds of images into a single image that can be mapped onto a globe.

The Earth floats delicately in space, sunlight illuminating the fluid mottling of white clouds suspended over its surface. The scene, the leading sequence in a recent NASA video about ship pollution and clouds, shows our planet from a perspective only a satellite or spacecraft could provide.

However, no camera captured that image of the Earth. The reason? It’s not one image. Instead, the single cloud-scattered globe is a mosaic of 298 smaller images of close-up areas of our planet meticulously stitched together by Helen-Nicole Kostis, a NASA science visualizer.
