Magma oceans are vast fields of surface magma that exist during periods of a planet 's or some natural satellite 's accretion when the celestial body is completely or partly molten. [1] In the early Solar System, magma oceans were formed by the melting of …

Mar 27, 2025 · There is a burgeoning scientific interest in the magma ocean, with research focused on understanding the characteristics, diversity, and potentially significant role it plays in the origin of life on Earth and beyond.

Aug 21, 2024 · There was once a magma-filled ocean on the south pole of the moon, scientists recently discovered after analyzing lunar soil that revealed ancient information about the moon's origin.

Nov 23, 2015 · The rotation of the newborn Earth may have helped to control the evolution of a giant magma ocean sitting on top of its core, researchers say.

Apr 29, 2019 · Moon formation by a giant impact ejecting material from a magma ocean on Earth reconciles geochemical and dynamical constraints on its formation, according to numerical simulations.

Sep 21, 2023 · Astronomers use “magma ocean” and “lava planet” to refer to the very hot molten period of a young rocky planet just after its formation. The theory is that, fingers-crossed, these planets would eventually cool down and form a solid outer crust, like Earth.

Mar 12, 2021 · As the Earth recovered and cooled after its chaotic collisions, its deep magma oceans crystallised and solidified, beginning Earth’s journey to the planet we know today.

Dec 20, 2022 · A magma ocean is a layer of molten rocks of approximately uniform depth that behaves rheologically as a liquid, is globally distributed, and makes up a substantial volume fraction of a planetary body (e.g., Taylor and Norman 1992; Tonks and Melosh 1993). Smaller, more localized magma bodies may also be referred to as magma ponds.

Oct 1, 2018 · In this paper, we review some of the ways in which magma ocean models for the Earth, Moon and Mars match present-day observations of mantle reservoirs, internal structure and primordial crusts, and then we present new calculations for the oxidation state of the mantle produced during the magma ocean phase.

Jun 22, 2018 · What?! A magma ocean? That’s right, a magma ocean. Think of it as a body of magma, consisting of a mixture of molten or partially-molten rock, volatiles (dissolved gas and gas bubbles) and solids (suspended crystals).
