Elsewhere in the solar system there was armor of life like Earth

Space rock samples brought back to Earth by NASA half a century ago reveal more surprises about the past of what is said to be “twice life” – the moon.

Scientists have long believed that Earth’s moon, which is smaller than many of the moons of Jupiter, Saturn…, would not be large enough to have a magnetic field of its own. But lunar rock samples collected by other NASA Apollo astronauts 50 years ago prove otherwise.

The discovery, which is said to have puzzled scientists, has just been announced by researchers from Brown University in Rhode Island.

According to the Daily Mail, analysis results show that these stones must have been formed in an environment with a strong magnetic field. It is Earth scientists themselves who still use paleomagnetic data in rocks to learn about the history of the Earth’s magnetosphere, so the evidence from rocks is extremely reliable.

They suggest that the early moon generated itself a discontinuous but powerful magnetic field during its early geological activity – before turning into the solid rock mass it is today.

In that past, the moon had a giant magma ocean like the Earth in the Great Fire City. Inside that ocean, giant rocks sink through the liquid mantle, creating a magnetic field. This formed within the first 1 billion years.

This is an important discovery because the magnetosphere is considered to be the armor of each planet, a necessary condition for life on a celestial body to be protected if it is fortunate to be born. The magnetosphere created by the Earth’s powerful magnetic field is a necessary layer of “life armor” whose waning times are often associated with mass extinctions.

Before that, a study published in Astrobiology in 2018 authored by a team of astrobiologists from Washington State University (WSU-USA) and University of London (UK) showed that the moon could have appeared. Early life form was twice as similar to Earth’s cyanobacteria, but then became extinct.
