New experiments performed in an ultra-high vacuum and temperatures of 10–16K confirm the importance of a new chemical pathway for the formation of methanol on interstellar ice grains.
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.
