Scientists have identified for some time that Mars at the moment lacks a magnetic subject, and lots of blame that for its paltry ambiance – with no protecting defend across the planet, the photo voltaic wind was in a position to strip away a lot of the gaseous ambiance over the course of billions of years. However, proof has been mounting that Mars as soon as had a magnetic subject. Outcomes from Perception, one of many Crimson Planet’s landers, lend credence to that concept, however in addition they level to a wierd function – the magnetic subject appeared to cowl solely the southern hemisphere, however not the north. A group from the College of Texas Institute for Geophysics thinks they may know why – in a latest paper, they described how a completely liquid core in Mars may create a lopsided magnetic subject just like the one seen in Perception’s information.
