A village in Kent is home to what is thought to be the world's largest scale model of the solar system and beyond, created to ...

For decades, the solar system set the template: small rocky planets close to the star, gas giants farther out, beyond a boundary called the snow line where icy grains help cores grow fast enough to ...

Key science: Stellar dynamics, N-body simulations, planetary orbital stability, and galactic gravitational potentials.

Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion resonances, probably ...

Over the course of more than two decades, researchers at the University of Bern have developed the so-called "Bern model," a suite of computer programs that can numerically simulate the formation of ...

Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

In the remote outer reaches of planetary systems, far beyond the orbit of known planets, enormous and mysterious worlds silently loop around their stars. Some drift as far as 10,000 times the distance ...

Sun-like stars are born from the gravitational collapse of the dense cores of molecular clouds comprised of dust and gas 1,2. Different generations of solid material are present in these dense cores, ...
