Blue straggler stars in old open clusters predominantly appear near the terminal-age main sequence because mass transfer from asymptotic giant branch donors enriches their cores with helium.
Post-perihelion UVES spectra of interstellar comet 3I/ATLAS reveal elevated NiI and FeI production explained by direct sublimation of Ni(CO)4 and Fe(CO)5 from subsurface layers, with a transient heat source accounting for the pre-perihelion Ni excess.
Three accelerating stars yield one stellar companion at 166 AU, one 45 Jupiter-mass object at ~18 AU, and one 9.5 Jupiter-mass object at 6.4 AU that is 65% likely to be a planet.
JWST observations of 133P/Elst-Pizarro yield water outgassing rates of (1.9 ± 0.6) × 10^25 and (1.4 ± 0.4) × 10^25 molecules/s at true anomalies 8° and 37.4°, with hypervolatile depletion Q(CO2)/Q(H2O) < 0.009 and an average log(Afrho/Q(H2O)) = -24.6 ± 0.2 across three MBCs.
Multi-phase molecular gas in IRAS20551-4250 is dominated by cold CO, shows UV-heated warm H2, tidal features from a merger, and no molecular outflows, consistent with ongoing star formation.
TOI-7154b is a 71.7 M_J brown dwarf in an 8.86-day eccentric orbit around a G star, with eccentricity and age suggesting stellar-like fragmentation origins.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.
A convLSTM classifier identifies lensed SNe Ia in simulated LSST-like time series, reaching ~60% true-positive rate at O(10^{-4}) false-positive rate by the seventh epoch even after adding realistic PSF variations and foreground SN contaminants.
Optical follow-up of 32 Planck SZ candidates yields photometric redshifts and richness estimates confirming 18 (7) as at least half as rich as expected at z>0.5 (z>0.8), highlighting Eddington bias and projection effects.
