General relativistic hydrodynamics simulations show that the more asymmetric the merger of two neutron stars, the heavier the r-process elements that are synthesized in the aftermath of the collision.

Researchers describe a “green” reconnaissance mission to a lava tube on the Moon; green missions take into account potential contamination to science targets from rocket exhaust, among other factors.

For low-mass stars, fast rotation is correlated with large-amplitude variability at optical wavelengths, which could be the result of heating by Alfvén waves or the result or small and frequent flares.

Several candidate high-redshift galaxies in JWST data are unknown in nature, as they cannot be explained by usual contaminants but are more numerous and more luminous than our theories would suggest.

Researchers suggest that the X-ray emission from the radio lobes of Pictor A is due to synchrotron radiation from high-energy (10–100 tera-electronvolts) electrons spiraling around magnetic field lines.

The full data release of a survey of the inner galactic plane will be useful for astronomers studying the properties of individual molecular clouds as well as structures within the Milky Way’s spiral arms.
