However, the latest WMM update follows a period of highly unusual activity for the magnetic north pole. In 1990, its northern drift accelerated, increasing from 9.3 miles (15 kilometers) per year ...
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
