A newly discovered distribution of dense, warm gas around a protostar, roughly in the shape of the number “9,” is unlikely to be solely due to outflows and instead may be caused by magnetic flux redistribution.

During its year-long prime mission in 2026-2027, Pandora will likely constrain the abundance of water and methane to ~1.0 dex for the atmospheres of sub-Neptune and hot-Jupiter exoplanets.

Archival data from the Chandra X-ray Observatory and the Very Large Telescope reveal the temperature, density, and thermal energy of the wind from a low-luminosity active galactic nucleus.

Combining strongly lensed gravitational wave signals with luminosity distances from their host galaxies, the Hubble constant could be measured in a way that is complementary to electromagnetic methods.

Modeling suggests that even planets within their stars’ habitable zones may become uninhabitable if they do not have a sufficient water inventory to balance their carbon cycle.

ZTF19acnskyy may be the first X-ray quasiperiodic eruption source to display correlated ultraviolet emission — another strange behavior that researchers must explain for this already unique source.
