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.

Using JWST, researchers have detected two candidate galaxies at redshifts of 15.7 < z < 16.4 — galaxies that may be the ultraviolet-bright precursors to other bright galaxies spotted at slightly lower redshifts.

Thermal infrared observations from the Very Large Telescope yield an upper limit of 17 meters for the diameter of the asteroid 1998 KY26, which Hayabusa2 will reach in 2031.

Using 16 years of observations from the Chandra X-ray Observatory to assess X-ray variability of 78 active galactic nuclei in dwarf galaxies, researchers find few instances of tidal disruption events.

During its commissioning and pilot phases, the Wide Field Survey Telescope stared at the galactic plane for 13 hours, leading to the discovery of a variable hot white dwarf and an ellipsoidal white dwarf binary.

New high-resolution near-infrared spectra of nine stars reveal the chemical abundance trends for more than a dozen elements, providing clues to the formation history of the Milky Way’s nuclear star cluster.
