A recent breakthrough in planetary science reveals the first-ever detection of lithium in Mercury’s exosphere—a result ...

A rare magnetic signal revealed lithium on Mercury, showing the planet is still being reshaped by meteoroid strikes.

Using a cutting-edge magnetic wave detection technique, a new study in Nature Communications has identified lithium in ...

Mercury, the innermost planet of our solar system, has always been a world of extremes,scorching days, freezing nights, and an airless, cratered surface. Though visited by spacecraft early on, much of ...

Because Mercury rotates so slowly — once every 58 Earth days, compared to a Mercury year, a complete trip around the Sun, lasting only 88 Earth days — the part of the planet at dawn spends a ...

When electrons from solar wind, accelerated by Mercury’s magnetic field, rain down on the barren ground near the planet’s poles, minerals in the ground react by fluorescing, or emitting x-rays.

These damaging waves of radiation are smacking into AU Mic b, which is located just 6 million miles from the star — a tenth of the distance between our sun and its closest planet, Mercury. As ...
