Three new candidate ancient planetary nebulae, each several arcminutes across with extremely low [O iii] surface brightness around 30 mag arcsec^{-2}, were discovered using amateur telescopes, with candidate central stars yielding age estimates of 50-100 thousand years.
JWST transits of TOI 700 d and e yield no exomoons, refined ephemerides, and identify 16-minute correlated noise that currently blocks Luna-analog moon detection.
VLBA observations of Orion young stellar binaries yield Keplerian orbits and dynamical masses for four systems, with two showing agreement to SED-based estimates and one confirming an intermediate-mass star with nonthermal emission.
A JWST MIRI LRS eclipse of HD 3167 b is 38±11 ppm, >5σ below a dark bare-rock prediction, implying an atmosphere on this ultra-short-period super-Earth.
Neural network derives LAMOST instrumental profiles from arc lamps and reduces RV dispersion by ~3 km/s.
Derives Teff, log g and metallicity for 282 M dwarfs via χ² fits of updated PHOENIX models to simultaneous visible+NIR CARMENES spectra, finding visible and combined ranges superior to NIR alone.
