It is widely accepted that the early Earth largely consisted of molten magma, forming a global ocean of magma. This extreme state of Earth was likely caused by the intense heat generated from accretionary impacts, meaning ...

In the search for potentially life-supporting exoplanets, liquid water is the key indicator. Life on Earth requires liquid water, and scientists strongly believe the same is true elsewhere. But from a great distance, it's ...

A volcanic eruption that has engulfed homes in an Icelandic fishing port confirms that a long-dormant faultline running under the country has woken up, threatening to belch out lava with little warning for years to come, ...

At nearly 65,000 kilometers long, the mid-ocean ridge system is the longest mountain range in the world. Running beneath the ocean's surface, mid-ocean ridges are formed at divergent plate boundaries, where tectonic plates ...

Jupiter's Io stands apart from the solar system's other moons, with its numerous volcanoes and its surface dominated by lava flows. Io's surface volcanism was confirmed in 1979 when the Voyager spacecraft imaged it, but its ...

Early in the formation of Earth, an ocean of magma covered the planet's surface and stretched thousands of miles deep into its core. The rate at which that "magma ocean" cooled affected the formation of the distinct layering ...
