United States: Presences of magnetic fields being protective were one amongst important ingredients which helped in thriving of life on Earth. This factor is differentiated from Earth’s liquid waters, rocky planet’s surfaces and atmospheres blanketing. Newer studies have found this. Studies of younger Sun alike star namely Kappa Ceti showed that magnetic fields play key roles in creating planet earth conducive towards life.
For being having habitat existence, planet requires water, warmth and there are requirements of being sheltered from violent young Sun. This is said by Jose-Dias Do Nascimento of the Harvard-Smithsonian Centre for Astrophysics (CfA) in US and University of Rio Grande do Norte (UFRN) in Brazil. Kappa Ceti is situated 30 light-years in Cetus whale constellation.
Teams calculated ages only of 400 to 600 million years old. This agrees with ages estimated from periods of rotations. These ages correspond roughly to times when life appeared firstly on Earth. As results by studying Kappa Ceti we get insights of early histories of solar system. Scientists told. Kappa Ceti is too much active magnetically. Its surfaces are blotched with lots of starspots sunspots giant.
It propels also steady streams of ionised gases or plasma out onto space. These stellar winds are 50 times strong when compared with solar winds of our sun. Stellar winds fierce batters atmospheres of different planets in habitable zones. Planets are shielded by magnetic fields.
