New Hubble Space Telescope observations allow researchers to constrain the properties of the stellar wind of Arcturus, a star that is prominently visible in the Northern Hemisphere sky.
Machine learning algorithms often ignore measurement uncertainty, but a newly developed method presents a way to include this uncertainty in the classification of high-redshift quasar candidates.
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.
