Prediction: More gas-giants will be found orbiting Sun-like stars



Washington DC (SPX) Feb 22, 2017
New planetary formation models from Carnegie's Alan Boss indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn. His work is published by The Astrophysical Journal. The population of exoplanets discovered by ongoing planet-hunting projects continues to increase. These discoveries can improve models that predict where to look for more of them. The planets predicted by Boss in this study could hold ... read more

The Earth's core consists mostly of a huge ball of liquid metal lying at 3000 km beneath its surface, surrounded by a mantle of hot rock. Notably, at such great depths, both the core and mantle are subject to extremely high pressures and temperatures. Furthermore, research indicates that the slow creeping flow of hot buoyant rocks - moving several centimeters per year - carries heat away f ... more
