Scientists Finally Figured Out Why Earth Twinkles From Space

Because satellites began to look at Earth from deep space, they saw a bright and bright mystery sparkling sparks. But Earth is a planet, not a star, so why do distant observers shine? This question has concerned scientists, including the famous astronomer Carl Sagan, for years, but now, reports the flower of St. Nicholas, New York Times, a NASA research team finally understood why.

In a new study published in the journal Geophysical Research Letters, researchers explain the secret of the apparent spark of the Earth in space: ice.

The Climate Deep Space Observatory (Discovr), a satellite designed to alert scientists to coronal mass ejections of the sun behind in space about a million miles from Earth. He saw the strange looks of our planet since he began to make observations in 2015.

The scenes were first recorded in a 1993 article by Carl Sagan and his colleagues, who examined images taken from Earth by the Galileo spacecraft as they headed for Jupiter. At that time, scientists have observed that lightning seemed to occur in water.

When Discovr launched, writes St. Fleur, the public began to ask Alexander Marshak, the author of the newspaper, in the reflection. He found the role of Sagan, but realized that the flashes of Galileo’s photographs were not limited to bodies of water. Intrigued, he worked with a team to study a year of Discovr data to find the origins of the flashes.

The team examined more than 800 blinks on images taken by Discovr, taking into account the latitude, angles and oxygen uptake in the Earth’s troposphere. Their source was reduced to sunlight and found to correspond to the places of cirrus. These tenuous clouds are composed of ice crystals that form in the upper troposphere. And the team believes that the horizontal ice particles in the clouds reflect sunlight, which can be identified even in deep space.

This means that the blink is very different from the one that humans put in the stars. These flashes occur due to the turbulence of the air on Earth that refracts the light from the stars, creating the illusion of a staggered form.

The distinctive blur of the Earth, on the other hand, is due to its water, and the technique could one day be used to identify other water-rich planets. In a news release, Marshak said he is trying to determine how the horizontal particles are actually able to use them to learn more about how Earth interacts with its own distant star.
