There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

Add Yahoo as a preferred source to see more of our stories on Google. Earth's rotation is slowing down, and it could be why we have oxygen for life Ever since its formation around 4.5 billion years ...

The precipitation of salt out of sea ice created a feedback mechanism that might explain the formation of Snowball Earth, the most extreme climatic event in the history of our planet. The idea, ...

When we start talking about Earth's origin, there are many theories on the table that have been tossed around for years, with the Big Bang hypothesis often leading the charge. But thanks to the James ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...

Our magnetosphere plays the role of gatekeeper, repelling unwanted energy that's harmful to life on Earth, trapping most of it a safe distance from Earth's surface in twin doughnut-shaped zones called ...

Proto-Earth is the term used to describe the earliest days of our planet, the body from which our pale blue dot evolved. At this stage of its geological evolution, it likely existed only for a ...

New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, carving out rings and gaps that ultimately explain one of the ...

Earth is about 4.5 billion years old, halfway through its expected lifespan. It will remain habitable for another 4–5 billion years, but rising temperatures from the aging Sun may challenge complex ...

Old crystals found in Western Australia are drawing fresh attention from geologists studying the formation of Earth. These minerals, called zircons, have been dated to be older than four billion years ...

Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.
