Planet Mars is at the center of a very important new discovery that was officially announced today, and here we are talking about something that has eluded researchers around the world for many decades. It seems that the planet Mars has a magnetic field whose activity started much earlier than initially thought, or at least that's what the researchers of the University of British Columbia say after a new detailed analysis of the planet.
Planet Mars it had the magnetic field used to reduce the impact of solar winds on the surface, but also to prevent particles charged with energy from the sun to enter the atmosphere. The planet Mars has not had an active magnetic field for an extremely long time, being one of the few planets in our solar system that lacks one, which of course has generated many theories and question marks.
Planet Mars: The AMAZING Discovery That Surprises the World
Planet Mars it still has so-called "crustal" fields, which create magnetic fields that protect the planet from solar winds and energy-charged particles. These fields were absent 3.9 billion years ago on the planet Mars, and researchers thought that the former magnetic field was inactive only since then, but in reality it seems that it disappeared 3.7 - 4.5 billion years ago, unlike a few hundreds of millions of years counting a lot.
"The absence of crustal magnetic fields above the Martian Hellas, Argyre, and Isidis basins is often interpreted as evidence of a time earlier, 4,1 billion years (Ga), or late, after 3,9 Ga ago. We revise these interpretations using new MAVEN magnetic field data. Weak fields are present on the 4,5 G old Borealis basin, with a transition to strong fields correlated with the basin edge. Magnetic fields, confined to a near-surface layer, are also detected above the ancient 3,7-Ga Lucus Planum.”
Planet Mars it would have had a magnetic head both 4.5 billion years ago and 3.7 billion years ago, and researchers believe that it disappeared and reappeared between these two periods. They believe that the formation of some hydrological basins would have led to the reappearance and in the end the total disappearance of the magnetic field on the planet Mars, and so they came to the conclusion that there is a difference of several hundred million years between the initial calculations and those of now.
Planet Mars it hasn't had that magnetic field for a long time, but it's interesting to see what exactly happened from the past to the present moment with the solar wind protection system.
