The combination of data and binary neutron star merger simulations shows that the source of GRB 230307A is unlikely to be a globular cluster; a disk origin is possible but requires finely tuned conditions.

A search for extragalactic exoplanets in data from the Transiting Exoplanet Survey Satellite detected none, but the analysis suggested that investigations of additional stellar streams may find these sought-after worlds.

In a survey of five protoplanetary disks, researchers find ice features, CO:CO₂ mixtures, micron-sized dust, atomic and molecular gas, polycyclic aromatic hydrocarbons, and more.

Using weakly and strongly alkaline materials frozen under vacuum conditions similar to those on Enceladus, researchers have shown that Raman spectroscopy can distinguish between critical mineral phases.

Detailed imaging and spectroscopy have revealed the behavior of a prominence eruption, showing evidence of transverse motions that are consistent with Alfvén waves.

The ultimate fates of the Milky Way and its neighbor Andromeda remain uncertain, with proper motion measurements with uncertainty less than 2 microarcseconds per year needed to reach a firm conclusion.
