You can learn more about the history and evolution of the Sun by visiting The Moon.
Scientists from the University of California, Berkeley recommended this as a way to better understand the star’s life history.
All the Solar System bodies have always been influenced by the Sun. We receive heat, light and solar wind from the Sun.
This is happening not only today, but every single day in the past. 4.5 billion yearss.
The ancient history of the Sun’s influence over us has disappeared on planets like Earth. Weathering from wind, erosion from water and the constant cycles in plate tectonics remove any modifications that the Sun made to our crust, either burying it or blowing it away.
According to a, dead worlds make better record keepers. New white paperRecently published in the preprint journal ArXiv.
The Moon is our nearest dead world, so it’s the ideal target for the Artemis series of missionariesWe should be looking for them.
Although there have been some surface activities on the Moon since its formation, such as lava flows and impacts from asteroids or comets, they are not insignificant. According to the whitepaper that activity on the Moon is a blessing rather than a hinderance,
Large sections of the Moon’s surface can be sealed off by lava flows. If we were able to get down below the flows and into deeper regolith on the Moon, then we could take a look at solar history before the lava flowed.
Impacts can mix things up but they also reveal deeper layers beneath the surface. This allows us to get to them easily.
Researchers identified a few key quantities we can measure using lunar samples, and how they relate to the Sun’s activity.
We can, for example, look at the time a sample has been exposed cosmic rays and then use that information to calculate the rate of cosmic radiation production from the Sun over the past billion years.
You can also see tracks left by high energy particles as they burrow in the crust for that information.
As the sun’s radiation increases, lunar soil gradually transforms into breccia. Comparing different samples from different locations and depths can help us understand how the Sun’s brightness changes over time.
According to the whitepaper, there is no better place in the Solar System for observing the Sun’s ancient history.
Simply put, the Moon acts as a solar time capsule.
