Scientists believe that two asteroids might be fragments of long-lost "planetary embryos" from the early solar system.

The formation of our solar system from a singular nebula raises an intriguing question: why did each planet develop with a ...

These situations allows scientists to investigate the usually hidden interiors of terrestrial worlds. Two teams of astronomers, including the observed planet's discoverers, now intend to join up ...

These rocky bits eventually coalesced to form the terrestrial planets. However, at a distance of around 4 astronomical units from the Sun (AU; 1 AU is the average Sun-Earth distance of 93 million ...

Because many close-matching simulations had the planet-like object swooping through the inner solar system, the researchers created an additional 10,000 simulations including the terrestrial ...

The research reveals that high-mass planets—or in other words, terrestrial planets—tend to form around stars with higher [Fe/H] and younger stars compared to low mass. Similarly, those with a ...

"It's a remarkable and fortuitous opportunity to understand terrestrial planet interiors," he added. The Penn State team trained JWST's spectrograph at K2-22, a star discovered by the Kepler ...

A new climate modeling study published in the journal Science Advances by researchers from the IBS Center for Climate Physics ...
