A new modeling method allows for researchers to determine the temperature of a starspot from just one passage of an exoplanet over the spot, as demonstrated by modeling of the K dwarf HAT-P-11.

New calculations of collisional cross sections of certain elements can improve our molding and our understanding of kilonovae, the explosions caused by colliding neutron stars.
Daniel C. M. Palumbo et al 2023 ApJL 952 L31
Creating an extremely long baseline interferometer, such as could be achieved by placing a detector in space or upping the frequencies of our Earth-bound detector, could enable studies of black hole photon rings.

Neutron stars, the exceptionally dense remnants of massive stars, might contain cores of quark matter — a possibility that could be distinguished from a nucleonic core by future gravitational wave observations.

Placing a lander on the surface of Saturn’s moon Enceladus is astrobiologically appealing but logistically challenging; models suggest that the icy, powdery surface must be at least somewhat compacted for landing to succeed.

Astronomers may have detected the first Y-type subdwarf, expanding our sample of brown dwarfs at the extreme low mass and temperature end of the spectral typing sequence.
