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

A computer visualization maps small bodies in the solar system that are expected to be observed by the Rubin Observatory during the 10-year Legacy Survey of Space and Time. Red indicates near-Earth ...

Parallel N-body simulations form the computational backbone for modelling the dynamical evolution of astrophysical systems, from planetary rings and protoplanetary discs to galaxy clusters and ...

Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of ...

NASA has finished building the Nancy Grace Roman Space Telescope, and its single most ambitious exoplanet goal is to detect ...

Rocky planets are typically found near their star, while gas giants form farther out — not the other way around. When you purchase through links on our site, we may earn an affiliate commission.

Scientists have discovered a bizarre planetary system where a rocky world orbits farther out than giant gas planets, defying long-standing theories of planet formation. The finding hints that some ...
