Earth is so far the only known planet on which life exists—with liquid water and a stable atmosphere. However, the conditions were not conducive to life when it formed. The gas-dust cloud from which ...

Scientists are exploring the origin of life's ingredients on our planet. A recent study suggests that essential volatile compounds, such as hydrogen and carbon, may have come from a cataclysmic impact ...

For decades, astronomers have tried to determine how Pluto acquired its unusually large moon Charon, which is about half the size of the dwarf planet. Now, new research suggests that Pluto and Charon ...

Apollo samples provide evidence: Researchers analyzed Moon rocks brought back by the Apollo missions and, for the first time, used their iron isotope ratios to trace where Theia originally formed.

A collision between Earth and a massive Mars-sized protoplanet likely caused the formation of our moon. Now scientists from the Max Planck Institute suggest that doomed planet was likely a rowdy ...

(CNN) — For decades, astronomers have tried to determine how Pluto acquired its unusually large moon Charon, which is about half the size of the dwarf planet. Now, new research suggests that Pluto and ...

The “demoted” dwarf planet Pluto and its largest moon Charon make an unusual pair, and for decades, scientists have been discussing how the binary system—in which each mutually orbits the other—came ...

Scientists at The Australian National University (ANU) say the early Earth was likely to be barren, flat and almost entirely under water with a few small islands, following their analysis of tiny ...

A new study published onarXiv by researchers from UC Berkeley, led by theoretical physicist J.J. Zanazzi, reveals that giant impacts between young gas giants can trigger seismic oscillations lasting ...

The planet "splashed down" into the star, sending a giant plume of gas into space that gave the star a ring. The James Webb Space Telescope (JWST) has been studying the scene of a dramatic collision ...
