Europa’s Icy Surface to Glow Bright Like Radium at Night
Here’s the recent news from space!
NASA researchers have found that one of the moons of Jupiter, Europa has shown evidence of glowing at the night. The scientists reached this great discovery after conducting an experiment at NASA's Jet Propulsion Laboratory (JPL) in California. During the experiment, they unearthed the long-hidden property of Jupiter’s ocean-filled moon and stated that Jupiter’s hits the surface of Europa day and night, which the latter relentlessly bears. The zapping of electrons and various other particles on the moon’s (Europa) the surface makes it to produce high energy radiation and these very radiation particles have shown hints of glowing in the dark.
Scientists made use of a device called spectrometer in order to separate light into different wavelengths and then connect them to different compositions of ice to see how they react. The experiment was done on a moon-like Europa, exploiting the sunlight that reflects on the moon’s dayside. This time, the results were collected in the dark which showed that Europa illuminates at night. In addition to this, the scientists also mentioned that the discovery of Europa glowing in the night can help in acquiring more information about its surface composition. In fact, the composition will reveal if Europa can sustain life in any form and will also assist in learning more about what actually lies beneath this ocean-filled moon.
There have been various researches on Europa earlier as well, in which the scientists discovered that the major components of its surface is most likely to be of salts such as sodium chloride & magnesium sulphate and ice too. However, this latest research will help them to know much more. These very salts were incorporated in the experiment into the water (under Europa like conditions) and were then blasted with radiation. The blast caused it to produce a glow and in fact, the glow seemed different with different compositions of ice.
The lead author of the work, Murthy Gudipati mentioned that Europa wouldn’t have shined this bright if it didn’t produce any radiation. It would have looked our existing Moon, posing dark on the shadowed side.
Undoubtedly, this discovery has given new hopes to the scientists of making life possible at Europa. It is sure that they are soon to come up with more fascinating information about Europa leaving us all surprised.
