Somewhere green, somewhere white …
Research at NASA’s Jet Propulsion Laboratory has revealed this in detail. The radiation from Jupiter has a different effect on the elements in Europa, causing a different brightness. In some places it looks green, blue and white and the intensity of the glow varies. The scientists divided the light into different wavelengths with the help of spectrometers. The elements in the ice can be detected based on each spectrum.
Is there life in Europe?
Murti Gudapati, the lead scientist for this research, has said that it can also explore the possibilities of life in Europe. In reality, Europa has a large amount of internal ocean that occurs as ice on the surface. By investigating the surface, scientists can conduct more in-depth investigations of the elements underneath. 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 discovered that Europa’s surface may be composed of ice and magnesium sulfate (Epsom salt) and sodium chloride (table salt), based on previous experiments. New research has found that under ice-like conditions, these salts and radiation in the snow create a glow. After experimenting with snow of different compositions, the gloss also looked different. Now NASA is ready to send its mission to Europa Clipper in the 2020s. With this help, radiation on the surface of Europa will be studied.
Apart from our moon
To do this, the JPL team prepared the Ice Chamber for Europa’s High Energy Electron and Radiation Environmental Testing (ICE-HEART). He was taken to the Maryland high-energy electron beam facility and tried to see how the radiation would affect the organic material underneath Europa’s ice. During this time, it was found that different luminosities were observed in 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 remains in the dark but due to the radiation from Europa it glows in the dark.
