Researchers believe the study has important implications for the discovery of habitable exoplanets
Solar winds may have caused Mars to lose its atmosphere, according to a computer simulation study that confirms the long-held belief that planets have a way to prevent such harmful radiations in order to sustain life Protective magnetic fields are required.
While factors such as the existence of moderately hot, moist environments and liquid water determine whether a planet can host life, the studyPublished in Monthly notice of the Royal Astronomical Society, Note that the ability of planets to generate magnetic fields around them is an overlooked aspect.
According to scientists, Arnab Basak and Dibyendu Nandi of the Indian Institute of Science Education and Research (IISER) Kolkata, planets covering these magnetic fields can act like a protective umbrella protecting the atmosphere from the sun’s super fast plasma rod. Huh.
On Earth, he said that a geo-dynamo mechanism generates the planet’s protective magnetosphere – an invisible shield that prevents the solar system from destroying our atmosphere.
In the current study, scientists simulated two scenarios of the red planet – one considering a young Mars with its magnetic field, and the other with a planet without this force field.
Simulations showed that in young Mars, the magnetosphere may have acted as a shield that prevents the solar wind from getting too close to the planet’s atmosphere and thus protects it.
Without an internal magnetosphere, the researchers said that the solar air magnetic field may have first wrapped around, and slipped past Mars, which takes away parts of the planet’s atmosphere, eventually erasing it completely gives. He said the findings confirm the belief that the magnetosphere around the planets plays an important role in determining their ability to sustain life.
Alternatively, planets that lose their magnetic fields eventually become ineffective with the loss of their atmosphere, the scientists said.
Researchers believe the study has important implications for the discovery of habitable exoplanets through initiatives such as NASA’s James Webb Space Telescope and ISRO’s Exovaries Mission.
