A group of scientists made a new map of the radiation reaching Europe, the moon of Jupiter in order to facilitate the search for habitability and biofirms indices.
If we want to understand what is happening on the surface of Europe and how it is related to the ocean below, we must understand the radiation, "said Tom Nordheim, senior author of the study
. and how deep scientists should be on the surface of Europe, one of the most promising places in the solar system to look for the ingredients of life.
"When we look at materials that are emerging from the basement, what are we looking at, does that tell us what's happening in the ocean, or is that what happened to the materials? after their irradiation? "he questioned.
For the development of the study, Nordheim and his team observed they closely monitored the electrons that exploded on the surface of the moon, for which they used data from overflights [19659007] in Europe, made by the Galileo mission and the electronic measurements of the spacecraft Voyager 1 of NASA .
"If we want to understand what is happening on the surface of Europe and how it is related to the ocean, we must understand the radiation," said the main author. study, Tom Nordheim.
Research published in the journal " Nature Astronomy " indicates that radiation doses vary by location.
It occurs in areas around the equator and decreases near the poles, said the National Aeronautics and Space Administration (NASA).
The document also measures the depth of radiation, which [19659005] varies from 10 to 20 centimeters in areas of higher emission, as well as within one centimeter of depth to averages and high latitudes, towards the poles of the Moon.
Thus, scientists in future missions to Europe will know how deep they must drill, to find any biofirmation that can be preserved.
