Time Lapse From IIS

400 photos, for 11 minutes, was what was required to obtain this time-lapse image of Earth and stars from the International Space Station over Namibia and the the Red Sea. NASA astronaut Christina Koch captured these images.

The circular lines in the sky are stars. Those that are seen on the surface as dot traces of white and light yellow colors. The thin orange lines are active fires in Angola and Congo.

To the north, thunderstorms look like white flashes, and above the curved horizon you can see a yellow-green halo, a chemical luminescence effect, known as Airglow, which is difficult to appreciate from the illuminated Cities.

Traces that are grouped to the upper left side of the image, with apparently shorter paths, are stars near the angle at which the Station rotates.

Near the surface, due to the optical deformation produced by the atmosphere, just below the Airglow, some stars seem to jump and dive behind the horizon. The arcs that follow different paths than the stars are artificial satellites.

Astronaut Koch, who has been in the ISS for approximately eight months, took part in the first ex clusively female spacewalk, to replace some batteries, and shared via Twitter images of her experiences.
