Researchers use high-resolution observations from the Hinode satellite to constrain simulations of the solar meridional flow for the first time, reproducing the observed properties of the polar magnetic field.
Meet S/2023 U1, S/2021 N1, and S/2002 N5: these newly discovered moons of Uranus and Neptune are just 7, 14, and 23 kilometers across, respectively.
Collisions between stars can produce transient signals similar in brightness to supernovae; new analytic and hydrodynamic modeling examines the properties of these events.
Measurements of galactic half-light radii at different wavelengths, combined with an investigation of simulated galaxies, suggest that dust rather than inside-out growth is responsible for observed trends.
A first-of-its kind numerical analysis demonstrates that radio and X-ray precursor emission is generated by Alfvén waves in the magnetosphere of a neutron star in a close binary system.
An analysis of 57 nearby Sun-like stars shows that roughly half of these systems have habitable zones subjected to X-ray fluxes equal to or less than that of the Sun, making them promising locations for habitable planets.
