Day and night in one photo: the astronaut at the international space station creates a stunning picture of the & # 39; shadow line & # 39; from the earth
- NASA astronaut Christina Hammock Koch has a remarkably detailed view of the & # 39; shadow line & # 39; of the earth
- The view, shown from the international space station ISS, records how our planet changes from day to night
- Astronauts aboard the space station can see up to 15 or 16 sunrises and sunsets every day
NASA has released a remarkably detailed image with a view of the Earth's transition from day to night.
A beautiful view of the planet can be seen, as well as the & # 39; shadow line & # 39; of the earth, a rare sight where the separation between day and night can be seen with the naked eye.
The stunning photo was taken on Monday by astronaut Christina Hammock Koch aboard the international space station ISS.

NASA has released a remarkably detailed image with a view of the Earth's transition from day to night. The beautiful photo was taken on Monday by astronaut Christina Koch aboard the international space station ISS
Koch posted the photo from her personal Twitter account and noted that the unrealistic view can only be seen on ISS by astronauts a few times a year.
& # 39; The @ Space_Station loop over the day / night shadow line on Earth happens a few times a year, & # 39; Koch wrote.
& # 39; We are constantly in the sunlight and never come into the shadow of the earth from the sun, and the earth below is always in the morning or at dusk.
& # 39; Nice time to look at the cloud. #nofilter, & # 39; she added.
Astronauts aboard the ISS are used to spot enchanting visions of the sunrises and sunsets of the Earth.
Astronauts aboard the ISS (in the photo) are used to spot enchanting visions of the sunrises and sunsets of the Earth. The ISS runs about 220 miles above the Earth and completes one trip around our planet every 92 minutes, according to NASA
The international space station revolves about 220 miles above the Earth and completes a journey every 92 minutes, according to NASA.
It travels at an astounding 17,200 miles per hour, with which astronauts can see up to 15 or 16 sunrises and sunsets every day.
These are tens of thousands of sunsets and sunrises that are viewed during the course of a year. For example the retired American astronaut Scott Kelly observed 10,944 sunrises and breaks during his year in space.
A video divided by astronaut Ricky Arnold showed last year what it looks like to see the sun go down and then get up again when the ISS revolves around the earth.
Koch, who left for the space station on March 14 with colleague Nick Hague and Russian astronaut Alexey Ovchinin, will stay in orbit for 328 days, meaning she will likely see many sunrises and sunsets.
She will return to Earth in February 2020 and surpass the current record for the longest single space flight of a woman.

The current record holder, NASA astronaut Peggy Whitson, set the record with 288 days.
Koch joined Anne McClain of NASA, David Saint-Jacques of the Canadian Space Agency and Expedition 59 Commander Oleg Kononenko of Roscosmos aboard the ISS, bringing the crew from six members.
As part of Expedition 59, crew members will conduct more than 250 scientific studies for more than six months in areas such as biology, earth sciences, human research, natural sciences and technology development.
Seventy-five of the studies are new and have never been conducted in space.
Some of the studies are sponsored by the US National Space Station Laboratory, which Congress appointed in 2005 to maximize its use to improve the quality of life on Earth.
Highlights of upcoming studies are devices that mimic the structure and function of human organs, free-flying robots, and an instrument to measure carbon dioxide distribution throughout the Earth.
WHAT IS THE INTERNATIONAL SPACE?
The International Space Station (ISS) is a $ 100 billion (£ 80 billion) science and engineering laboratory that spins a 400-kilometer radius above the Earth.
It has been permanently manned by rotating crews of astronauts and cosmonauts since November 2000.
Research conducted on board the ISS often requires one or more of the unusual conditions in a low Earth orbit, such as low gravity or oxygen.
ISS studies have done research into people, space medicine, life sciences, natural sciences, astronomy and meteorology.
The US space agency NASA spends around $ 3 billion (£ 2.4 billion) a year on the space station program, a level of funding endorsed by the Trump administration and Congress.
A commission from the American House of Representatives overseeing NASA has begun to examine whether the program should be extended beyond 2024.
Alternatively, the money could be used to accelerate planned human space initiatives to the moon and Mars.
