The sun’s rays may have caused Mars to lose its shape, according to computer simulations that confirm the long-held belief that the planets need a protective magnetic field to block such harmful radiation in order to survive.
While factors such as the presence of warm, wet and wet conditions determine whether the planet can sustain life, this study, published in the Monthly Notices of the Royal Astronomical Society, noted that the planets’ ability to generate magnetic fields around the element is ignored.
According to the scientists, Arnab Basak and also Dibyendu Nandi from the Indian Institutes of Science Education and Research (IISER) Kolkata said that these planetary magnetic fields can act as a protective umbrella, shielding the atmosphere from the plight of the sun’s plasma.
On earth, they claim, a geo-dynamo machine creates a magnetosphere that protects the planet – an invisible shield that blocks the sun’s rays from destroying our atmosphere.
In the present study, scientists mimicked two aspects of the Red Planet – one looking at small Mars with its strong magnetosphere, and the other on a planet outside this field of energy.
Imitation has shown that on the small Mars, the magnetosphere may have served as a shield against the sun’s atmosphere and thus protected it from extinction.
Outside the inner magnetosphere, researchers have suggested that the magnetic field of the sun’s solar system may have begun to rotate, slipping away from Mars, carrying away part of the earth’s atmosphere and ultimately destroying it.
They also said that these findings reinforce the belief that magnetospheres around the planets and that it also plays a key role in determining their ability to sustain life.
Alternatively, the planets lose their magnetic field and end up emptying their air, scientists add.
Researchers believe the study has a significant impact on the search for exotic planets through space programs such as NASA’s James Webb Space Telescope and ISRO’s ExoWorlds mission.
