The eccentricities of binary stars that orbit one another within a few astronomical units follow a simple Rayleigh distribution, an outcome that may be traceable back to excitation by circumbinary disks.

A novel neural network architecture produces interpretable features that can be combined to estimate galaxy properties such as metallicity from pixel-level features.
Combining data from multiple sources, astronomers show that the stellar energy feedback from the OB association LH15 is powerful enough to have created the surrounding supergiant shell.
A dedicated telescopic search for potentially hazardous asteroids in the Taurid swarm yielded no detections, suggesting that there are no more than 9–14 objects with diameters larger than 100 meters in the swarm.
Probabilistic modeling shows that perturbations from dark subhalos can’t account for the Gaia “snail,” a spiral feature in the vertical phase-space distribution in the solar neighborhood.
The kinematics of stars in the central region of the massive elliptical galaxy Holmberg 15A reveal the galaxy’s central supermassive black hole to be one of the most massive in the local universe.
