The LIGO collaboration has discovered a remarkable pair of merging black holes; with estimated masses of 137 and 101 solar masses, these black holes appear to lie within or span the black hole mass gap.

For a sample of nine variable stars, stellar variability appears to have little impact on exoplanet equilibrium temperature or water retention, though more extreme variability may have a greater impact.

Modeling of outflows from the galaxies of Stephan’s Quintet shows the transition from active galactic nucleus–powered outflows at small radii to tidal flow powered outflows at larger radii.

When a bright star saturates the detector on JWST’s Mid-Infrared Instrument, the flux deficit that follows could produce false-positive exoplanet signals and degrade point-spread function subtraction.

The addition of a neural network to a foundational model used in solar wind forecasting enhances the flexibility of the model, allowing it to adapt to varying solar wind conditions.

Observations from multiple spacecraft stationed around our solar system revealed the longitudinal behavior of galactic cosmic ray flux decreases associated with a passing coronal mass ejection.
