New work makes progress on understanding precisely what happens in the interiors of stars going supernova, but even state-of-the-art simulations are unable to resolve the onset of convection in these stars.
The Cygnus Cocoon star-forming region in the Milky Way is a potential source of high-energy particles, and new estimates suggest that it’s capable of accelerating cosmic rays up to petaelectronvolt energies.
An analysis of 134 solar flares with a special magnetic field configuration reveals that these flares arise solely from active regions and are associated with radio bursts and jets about 50% of the time.
Researchers report the first definitive detection of fullerenes — complex molecules made solely of carbon atoms — in a meteorite, though the origins of these molecules are still unknown.
New high-resolution observations of a jet emanating from a protostar reveal intriguing new features, including episodic velocity variations of the jet and a collimated stream of ionized particles.
Simulations of the Transiting Exoplanet Survey Satellite’s observing performance predict that the spacecraft will discover 12,519 planets over 7 years, and it will discover progressively smaller planets over time.
