Joint speckle-atmosphere retrievals on JWST spectra of HD 19467 B and a field T dwarf detect H2O, CH4, CO, CO2 and NH3, yield carbon isotopic ratios of 154 and 85 respectively, and show near-solar metallicity with subsolar C/O.

LSST will image 18,000 square degrees of sky about 800 times across six bands over 10 years to a coadded depth of r~27.5, producing a public database of 40 billion objects and 32 trillion observations.
Stellar population synthesis of three AGN hosts shows recent rejuvenation and central metallicity drops consistent with gas inflows fueling both star formation and AGN activity.
The paper identifies three key science cases that will require Hubble's short-wavelength capabilities for exoplanet atmosphere studies into the 2030s.
