Will the moon of Jupiter Europa, shining in the dark darkness, be a sign of life?

Many tales have been written about the moonlight and the brilliance of our moon, from science to literature, but there is another moon in the universe, the beauty of which may soon be common. The moon of Jupiter (Jupiter) is Europa (Europa). Scientists have done several experiments in the lab to learn more about the environment of this full moon of ice and oceans. Jupiter emits a large amount of high-energy radiation on the surface of Europa. Due to their surface impact, Europa also glows in the dark, causing a very beautiful sight. (All photos: NASA)

Somewhere green, somewhere white …

Research in NASA’s Jet Propulsion Laboratory has revealed this in detail. The radiation from Jupiter has a different effect on the elements existing on Europa, causing a different brightness. In some places it appears green, blue and white and the intensity of the brightness varies. Scientists divided the light into different wavelengths with the help of spectrometers. Elements in the ice can be detected based on each spectrum.

Is there life on Europe?

Murti Gudapati, the lead scientist of this research, said he can also explore the possibilities of life on Europa. In fact, Europa has a large amount of inland ocean that comes in the form of ice on the surface. From research on the surface, scientists can do more in-depth research on the underlying elements. The special thing is that it is usually done with the help of sunlight but in the new results it was discovered how Europa glows in the dark.

Is it on the surface?

Scientists have found that Europa’s surface may consist of ice and magnesium sulfate (Epsom salt) and sodium chloride (table salt), based on previous experiments. New research has found that in ice-like conditions, these salts and radiation in the snow create a glow. After experimenting with the snow of different compositions, the brightness also looked different. Now NASA is ready to send its mission to Europa Clipper in the 1920s. With this help, radiation on the surface of Europa will be studied.

Apart from our moon

For this, the JPL team prepared Europe’s High Energy Electron and Radiation Environmental Testing (ICE-HEART) ice chamber. It was taken to the Maryland high-energy electron beam structure and looked to see how the radiation would affect the organic material under Europa’s ice. During this period it was found that different luminosities were observed at different ice compositions. The difference between our moon and Jupiter’s moon is that our moon shines with sunlight. So when there is no sunlight, it stays in the dark but due to the radiation from Europa it glows in the dark.
