Breathtaking: Watch an entire year of Earth pass before your eyes

The time lapse video that you can watch soon shows a whole year on our planet in just under three minutes. Recently shared by NASA, the clip was created from footage recorded by an instrument called EPIC aboard the space satellite DSCOVR - equipment that is in orbit between Earth and the Sun.

A terrestrial year

According to the clip's narration, the images you just saw above began to be captured by DSCOVR in mid-July last year, and the sequence is made up of over 3, 000 records. The space satellite is approximately 1.6 million kilometers away from Earth at a gravitational equilibrium point known as Lagrange 1.

Look at the fog around the earth

According to the narration, from this location, the equipment witnesses the sun rising in the west and setting in the east - because, unlike us, earthlings! - around 13 times a day. And about the fog that can be seen around the Earth, NASA people explained that it is the result of light scattering by molecules present in the atmosphere. Incidentally, it is because of the scattering of light that the sky looks blue during the day and reddish at dusk.

Blue world

And speaking of color, the hues that appear in the video are not exactly those recorded by DSCOVR instruments. In fact, they are a NASA estimate of how a person would see our planet if he could sit comfortably where the satellite is.

According to NASA, the EPIC camera captures at least one set of images every two hours, and each record is made at 10 different wavelengths. To achieve the result shown in the video, space agency specialists combined at least three of them - red, green and blue.

This "spot" on the planet is the shadow of the moon during the eclipse that took place in March.

If you have watched the entire clip carefully, you may have noticed that a huge shadow appears over the Earth - around the minute 1:52. This "apparition" is nothing more than the shadow of the moon being cast over the surface of our planet during a total eclipse of the sun that took place in March.

Cloud cover

In addition to eclipses and other events, NASA researchers can track cloud movement through the records. As they explained, approximately two-thirds of the planet is covered by them, and while many people prefer the cloudless sky, clouds help regulate the temperature of our world by reflecting sunlight and preventing surface heat from escaping into space.

Variations in cloud cover can interfere with the planet's thermal balance and affect how hot it can become. That's why NASA keeps an eye on cloud dynamics, and by combining this information with the captured images of the illuminated face of our world, scientists can study changes that occur daily across the planet to better understand and protect the earth. .

Finally, in addition to recording the movement of clouds and weather systems, the images allow scientists to study fixed features of the earth, such as forests, deserts, and the different oceans that cover the surface. As if little, through the records they can still monitor the levels of ozone and particulate matter in the atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of the planet!
