A magma that would freeze solid on Earth can keep flowing on Mercury, and sulfur is the reason. New laboratory experiments published in Geochimica et Cosmochimica Acta in early 2026 show that ...

Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and ...

A new experimental study published in Geochimica et Cosmochimica Acta reveals that Mercury’s sulfur-rich interior behaves in ways that challenge long-standing Earth-based models of planetary evolution ...

Although Mercury was geologically active in its early days, today its surface appears almost completely static. This is why it is often perceived as a dead and dry planet. A new study led by Dr.
