Evidence that rocky planets beyond Jupiter formed as rapidly, and at the same time, as the inner planets could transform our ...

The meteorite Northwest Africa (NWA) 12264 might cause changes to the timeline of planet formation, affecting the knowledge ...

“We wanted to find out whether the building blocks of Earth and Mars originated in the outer or inner Solar System”, says Dr. Christoph Burkhardt of the University of Münster, the study’s ...

Scientists previously determined that a magnetic field was present throughout the inner solar system—a region that spanned from the sun to about 7 astronomical units (AU), out to where Jupiter ...

Scientists have thought that our solar system's inner rocky planets — Mercury, Venus, Earth and Mars —formed first (around 4.566 billion years ago), while gas giants and icy bodies in the ...

In our solar system, Mercury, Venus, Earth, and Mars have period ratios of about 2.6, 1.6, and 1.9, respectively. Overall, the study showed that our solar system fits reasonably well into the team ...

Krypton from the Earth’s mantle, collected from geologic hot spots in Iceland and the Galapagos Islands, reveals a clearer picture of how our planet formed, according to new research from the ...

New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices ...

A new study by experts from Nasa and the University of Oxford suggests that Uranus gives out more heat than it receives from ...

Chiefly, the finding could help explain why Pluto, the largest known object in the Kuiper Belt — a vast region of icy bodies in the outer solar system — is dominated by rock rather than ice ...

Scientists have known that a magnetic field shaped the inner solar system, where Earth and the terrestrial planets were formed. But it was unclear whether such a magnetic influence extended into ...
