New Horizons measurements show that the solar wind speed is reduced by 5%–7% between 30 and 43 AU relative to the speeds at 1 AU, as the wind encounters an increasing amount of interstellar material.

Far-ultraviolet imaging of the nearby dwarf irregular galaxy IC 2574 indicates that star formation in the galaxy is partly triggered due to expanding H I holes, but in most sites, it’s driven by other mechanisms.

In the next stage of the Super-Kamiokande experiment, gadolinium sulfate will be added to the particle detector, potentially making it sensitive enough to be able to provide pre-explosion warnings for core-collapse supernovae.

Modeling based on the observationally reconstructed magnetic field of the 0.7 Gyr young Sun’s twin, k 1 Ceti, suggests that coronal mass ejections tend to propagate within a small cone about the ecliptic plane.

Redshifts are provided for all 1,041 Two Micron All-Sky Survey (2MASS) Redshift Survey galaxies that previously lacked this information due to their location in the Zone of Avoidance.

Despite the influence of the eccentric HR 5183 giant planet, there remain a narrow range of locations within the star’s habitable zone where terrestrial planets may reside in long-term stable orbits, dynamical simulations show.
