Cristoforetti wears a hot pink shirt, black pants with white stripes on the side, and blue running shoes and is watching a laptop in front of her. A white harness on her torso connects her to the sides of the green treadmill. Her legs are slightly blurred from the motion of her running and the entire image is tilted to the left so that she seems to be running down a steep hill.

Eventually, our Sun will run out of fuel and die (though not for another 5 billion years). As it does, it will become like the object seen here, the Cat’s Eye Nebula, which is a planetary nebula. A fast wind from the remaining stellar core rams into the ejected atmosphere and pushes it outward, creating wispy structures seen in X-rays by Chandra and optical light by the Hubble Space Telescope.
