NASA space agency finally found the secret behind the glow of “Europa”, one of the moons of Jupiter, as well as the mystery of its color change.
–
According to a recent study in magazine “Nature” science, as NASA discovered that the moon “Europa” shines in the dark as well as during the day, and changes its colors, and this is the result of the radiation emanating from Jupiter towards its shores.
The scientists added in their research that the salty compounds on the surface of the moon “Europa” interact with the radiation of Jupiter, resulting in a change of color to white, blue or green.
In order to make this discovery, NASA’s Jet Propulsion Laboratory used a “spectrometer”, a tool that analyzes components of light and measures its reflections on the surface of the ice Jupiter moon.
“This nocturnal glacier could provide additional information about the formation of the surface of the Moon,” Europa, “and it could give us clues about whether the moon is habitable on its surface, said Murthy Godebatti of the Jet Propulsion Laboratory.
????☢️ As Europa orbits Jupiter, it withstands relentless pummeling of radiation. But as the particles pound the icy ocean-filled moon’s surface night after night, day after day, they may also be doing something otherworldly: making Europa glow in the dark: https://t.co/LgaUpdVCt3 pic.twitter.com/t7uq4SBtmh

The surface of the moon “Europa” is composed of a mixture of ice and common salts, including magnesium sulfate (Epsom salt) and sodium chloride (table salt), but scientists did not expect that the icy structures would change the way the glow, so that each type of ice has a different spectrum.
In order to test this, NASA created an instrument called the “ice chamber”, whose mission is to evaluate the radiative environment and high-energy electrons in “Europa”, and their interactions with organic matter under the moon’s ice.
And previous studies on the moon “Europa” indicated that it may contain three times the amount of water that the planet contains, while its ocean depth reaches 62 miles, nearly ten times the deepest point on this planet.
