The NASA astronaut captured the colorful image in one of the 15 orbits of the planet's space station. Every day, the International Space Station (ISS) travels around the Earth about 15 times. During these orbits, each lasting an hour and a half, the ISS crosses the days and nights of the Earth. Frequent flybys offer NASA astronauts an unprecedented opportunity to photograph the fascinating phenomena of the planet.
In this spatial photo, Christina Koch photographed the phenomenon of the southern aurora known as Aurora Australis.
Aurora effects, or polar lights, are colored streams of excited gases that bubble up in the upper parts of the atmosphere.
Here, NASA astronauts saw bright, green lights illuminating the night near the South Pole of the Earth.
The physicist and expert in electoral engineering tweeted: "Years ago, at the South Pole, I inspired myself from dawn to inspire me during the winter night of six months.

When charged particles driven by solar winds spread over our planet, they interact with oxygen and nitrogen in the atmosphere.
These interactions excite the gases at high altitude to the point where they start to shine in various shades of green, blue, yellow, red and purple.
In the northern hemisphere, near the North Pole, the lights are known as Aurora Borealis or Aurora Borealis.

In the southern hemisphere, near the South Pole, aurora borealis are called Aurora Australis.
NASA said: "The dawn lights provide a spectacular view of the ground, but also captivate the imagination of scientists studying incoming energy and particles from the Sun."
But auroras are not the only fascinating sites that ISS astronauts can see every day.
On June 7th, Mrs. Koch tweeted a beautiful photo of the winding rivers of Madagascar for 250 km in space.

The NASA astronaut is currently part of the crews of the ISS 59 and 60 expeditions, which were launched in the orbital laboratory in March this year.
Ms. Koch graduated from NASA's Academy Program at the Goddard Space Flight Center (GSFC) in 2001.
She then worked as an electrical engineer at the GSFC Laboratory for High Energy Astrophysics between 2002 and 2004.
In 2013, she was selected among the eight members of NASA's 21st class of astronauts.
