Molecular Filament Shielded Young Solar System from Supernova

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially destroyed the nascent Solar System. New calculations shows that a filament of molecular gas, which is ...

Scientists Report 'Benchmarks' for Extreme Space Weather

Extreme space weather threatens vital satellites orbiting the Earth, including the Global Navigation Satellite Systems (GNSS) which pass through the heart of the outer radiation belt. New research has now determined a series of benchmarks for the likely severity of extreme space weather events in ...

Sun's Coldest Region Stores Secret to Heating Million-Degree Corona

Researchers have unveiled the discovery of intense wave energy from a relatively cool, dark and strongly magnetized plasma region on the Sun, capable of traversing the solar atmosphere and maintaining temperatures of a million degrees Kelvin inside the corona. Researchers say the finding is the ...

Flaring Star Could Be Down to Young Planet's Disc Inferno

New simulations offer new explanation for star's 85-year flare. In this scenario, a young giant planet is burning up very close to its star, suggesting solar systems may have hosted many of such planets that have since ...
