The Solar Energetic Particle (SEP) instrument detected low-energy gamma-ray photons and secondary charged particles that were generated when gamma-ray photons interacted with the spacecraft material.
A newly developed algorithm outperforms existing transit-detecting algorithms in 93% of trials when applied to a data set of rapidly rotating and active M-dwarf stars.
Roughly five years of asteroseismic modeling may reveal the interiors of blue supergiant stars well enough to determine if these stars are the products of binary mergers.

Research suggests that observations of gravitational wave “standard sirens” out to a redshift of z = 5 may enable an assessment of whether lambda CDM is really the best descriptor of our universe.

New chemical diagnostics allow researchers to distinguish gas clouds enriched in metals by the first generation of stars exploding as pair-instability supernovae from those enriched by other types of supernovae.
A new algorithm allows for the weighted stacking of astronomical radio images while removing interfering signals; the method is demonstrated with observations of the Andromeda Galaxy.
