Southwest Research Institute scientists propose a new model for the formation of compact exoplanetary systems that contain multiple rocky planets in tight orbits around their star. In this model, ...

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 ...

A conception that corresponds not only to our Solar System but also to most planetary systems identified to date. However, ...

LHS 1903 is a small red M-dwarf star that is cooler and shines less brightly than our Sun. Scientists used telescopes in space and on Earth to discover four planets orbiting LHS 1903. With those ...

Astronomers have identified a distant planetary system that appears to defy long-standing theories about how planets form. Located about 116 light-years from Earth, the system orbits the red dwarf ...

A maker has developed the Meridian Orrery, a 3D‑printed, ESP32‑powered solar system model that automatically positions planets and even includes a moon orbiting Earth. The device calculates celestial ...
