In 2013, the European Space Agency (ESA) launched a trio of Swarm satellites to monitor Earth’s magnetic field. According to a research paper published in Science Advances on Sept. 30, 2016, the satellites were able to measure a faint magnetic field created by oceans that led to discoveries about Earth’s electrical nature.
