Repeating and non-repeating fast radio bursts appear to originate from different progenitors, environments, or emission mechanisms — but intriguingly, both appear to be consistent with a magnetar origin.

A newly discovered brown dwarf companion to an M-dwarf star is estimated to have a mass just shy of 60 Jupiter masses; the object is accessible to many investigative methods and is likely to be a useful benchmark.

Early observations of interstellar interloper 3I/ATLAS revealed a compact coma, minimal light-curve variation, and a similar visible-light/near-infrared spectral slope to other interstellar objects.

A proposed mission would shepherd the asteroid Apophis through its close approach of Earth in 2029, seeking to study the asteroid’s interior and understand how its surface is altered by the encounter.

A long-term radio study finds that a Sedov–Taylor model can describe the evolution of a tidal disruption event without late-time rebrightening; this event is likely to be detectable for decades in the future.

For the first time, researchers have convincingly identified CaS and tentatively identified KS and KSH in the interstellar medium, advancing our understanding of how refractory molecules form in the gas phase.
