Researchers detect gamma rays from galaxies with molecular outflows — a way that gas is removed from galaxies, potentially suppressing star formation — and find that outflows might lead to more gamma-ray emission.

The central bulge of our galaxy may have the same stellar and brown dwarf initial mass function as the galactic disk, suggesting that brown dwarfs form in the same way that stars do.

A recent cubesat mission aims to detect the extended atmospheres of nearby exoplanets undergoing atmospheric escape — a process thought to play a fundamental role in the evolution of exoplanetary atmospheres.

The first observations by the Imaging X-ray Polarimetry Explorer of a weakly magnetized neutron star allowed researchers to place an upper limit on the object’s polarization and constrain its inclination.
A laboratory investigation of space weathering — chemical and physical processes that change the spectral properties of asteroids — suggests that the solar wind plays a dominant role in weathering.

Researchers have compiled a new catalog of 264 southern radio sources, a large portion of which have known optical and mid-infrared counterparts as well as redshift estimates.
