According to recent research, irregularities in the cooling process of molten iron in the Earth's core are responsible for variations in the planet's magnetic field.The swirling molten iron in the Earth's core controls the magnetic field /Credit: preparaenem.comWhy do satellite operations and compass readings experience interference that results in inaccurate directions not aligned with...
This system consists of a pair of galaxies, dubbed IC 694 and NGC 3690, which made a close pass some 700 million years ago. As a result of this interaction, the system underwent a fierce burst of star formation. In the last fifteen years or so six supernovae have popped off in the outer...
