Why does Mercury have such a big iron core? Magnetism!
A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of ou.....»»

Mission control is trying "restlessly" to save a spacecraft to Mercury
A joint European and Japanese spacecraft bound for Mercury has encountered thrust problems that could jeopardize the future of the mission. A complex mission to Mercury that began its epic space voyage six years ago has encountered critical thr.....»»
The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal
In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction......»»
