SN 2023fyq is the first Type Ibn supernova with a directly detected hot luminous progenitor consistent with a low-mass helium star in a binary system, based on pre-explosion imaging, disappearance confirmation, and multi-wavelength environmental analysis.

JWST observations find constant ~1% PAH abundance in the M82 superwind to 5 kpc, consistent with shielding in surface layers of cool clouds and possible replenishment.
The low-mass IMF in Boötes I is consistent with the Milky Way within 68% confidence for broken power-law and lognormal forms, indicating universality at low metallicity.
MORIA pipeline applied to HST data for KMT-2019-BLG-0253 halves the number of viable solutions and measures a 0.65 solar-mass host with a 7-9 Earth-mass planet at 2.64 kpc.
N6946-BH1's remnant is roughly 10 times fainter than its progenitor while stellar merger remnants are 10-100 times brighter, and asymmetric dust cannot explain the difference.
JWST TRGB distances to 10 SN Ia hosts update calibrations for 11 SNe yielding H0 of 68.4-69.6 km/s/Mpc and show modest shifts when combined with prior HST data.
A new HST wide-field survey of the Galactic Bulge supplies high-angular-resolution data to enhance Roman exoplanet detections and serve as a community legacy dataset for stellar populations and dynamics.
A multiband extension to crowdsource enables joint source fitting across bands with shared positions, improving flux consistency and reducing positional scatter compared to single-band processing.
