New research from The University of Texas at Austin adds evidence to a theory that claims the metallic cores of rocky planets like Earth were formed when molten metal trapped between grains of silicate rock percolated to the center of the planet during its early formation.

Taras Gerya at the Swiss Federal Institute of Technology in Zurich reviewed studies that modelled Earth's early formation and found that the process changed as the mantle cooled.

Inability to find rock formations from the period led them to conclude that early Earth was hellishly hot, either entirely molten or subject to such intense asteroid bombardment that any rocks that formed were rapidly remelted.

In trying to understand the formation of the early Earth, some researchers have suggested that the planet was dry and inhospitable to life until icy comets pelted Earth and deposited water on the surface.

This is a timeline of the history of our planet places the formation of the Jack Hills zircon and a «cool early Earth» at 4.4 billion years.

While on present - day Earth the carbonate formation is dominantly through organic processes (various shell - forming marine organisms are happy to make use of the CO2 dissolved in the ocean), in the early Earth and, presumably, in other Earth - like planets with little or no life the same process can occur inorganically, but somewhat slower, in silicate rock weathering.

Researchers uncovered a piece of volcanic rock dating back to the formation of Earth's early crust.

Until now, it has been generally accepted that a meteor constitutes a time capsule — a relic of the early creation of the solar system that has fallen to Earth, allowing us to delve into the distant past by looking at the composition of the essentially unchanged material that formed the basis of planetary formation.

This is in line with more recent studies that suggest that misalignment of magnetic field and rotation axes or turbulence may enhance early disk formation, producing disks of 100 times the Earth - Sun radius or larger.

Complex molecules in space are of interest for many reasons, including their possible connection to the formation of biologically significant molecules on the early Earth.

The leading theory for Charon's formation is that it formed similar to the way that the Earth and Moon have formed: from the accumulated orbital debris that surrounded Pluto after a giant impactor hit the latter during the early history of the Solar System.

However, the research team — which also included Sujoy Mukhopadhyay and Vicky Manthos of University of California Davis, Don Francis of McGill University, and Matthew Jackson, a Carnegie alumnus now at University of California Santa Barbara — was able find a geochemical signature of material left over from the early melting events that accompanied Earth's formation.

He has developed and applied a range of isotope geochemical and cosmochemical tools to shape our understanding of the origin of continental magmas, the formation of the continental crust and lithospheric mantle, the early differentiation of the Earth and Moon, and the chronology of the early Solar System.

Now, scientists at Rensselaer are turning these atmospheric assumptions on their heads with findings that prove the conditions on early Earth were simply not conducive to the formation of this type of atmosphere, but rather to an atmosphere dominated by the more oxygen - rich compounds found within our current atmosphere — including water, carbon dioxide, and sulfur dioxide.

Planetary scientists think that our relatively big Moon, and the axis tilt itself, were created by enormous collisions Earth experienced early in its formation 4.5 billion years ago.

Early this year I came across this: Jean Dickey of NASA's Jet Propulsion Laboratory, Pasadena: One possibility is the movements of Earth's core (where Earth's magnetic field originates) might disturb Earth's magnetic shielding of charged - particle (i.e., cosmic ray) fluxes that have been hypothesized to affect the formation of clouds.

Nevertheless, ancient Archaean lead ores of galena have been used to date the formation of Earth as these represent the earliest formed lead - only minerals on the planet and record the earliest homogeneous lead - lead isotope systems on the planet.
