JWST imaging reveals a z=0.92 disk galaxy with an X-shaped bulge, nuclear stellar disk, and extended disk whose bar geometry matches present-day systems, showing bar-driven secular evolution largely complete 7.6 Gyr ago.

An algebraic degeneracy makes all reionization-history observables sensitive only to the product of escape fraction and star formation efficiency, explaining parameter tensions and limiting dark matter constraints from reionization data.
Fermi-LAT detects point-like gamma-ray emission from SNR B0453-685, with broadband modeling favoring an evolved PWN impacted by the SNR reverse shock and possible pulsar contribution below 5 GeV.
Hinode/EIS full-disk mosaics show coronal intensity tracks solar cycle via active region coverage while velocity properties in log T~6.2 plasma remain stable across cycles 24-25.
In a bias-cleaned sample of main-sequence stars, magnetic activity above solar maximum accounts for non-detection of p-modes in 32% of cases where amplitude is predicted sufficient, while stars with photometric activity index above 2000 ppm have 98.3% probability of no detected oscillations.
Magnetic activity induces frequency shifts that bias asteroseismic age estimates by up to 10% and helium abundance by up to 3% in solar-like stars.
