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

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 ...

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, ...

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 ...

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 ...

NASA’s Nancy Grace Roman Space Telescope is predicted to detect more than 100,000 transiting planets during a single survey ...

More than one-third of the giant planet systems recently detected outside our solar system may harbor Earth- like planets covered in deep global oceans that offer abundant potential for life, ...

Stellar astronomy examines the life cycles of stars from their birth in dense molecular clouds to their ultimate fates as white dwarfs, neutron stars or black holes. Turbulence and gravity sculpt ...
