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.

A study of a well-known active M-dwarf star shows that the temperatures of its stellar flares are significantly lower than the canonical flare temperature of 10000K.

Using density functional theory calculations, researchers have shown that five of the six strongest diffuse interstellar bands can be attributed to carbon nanotubes that form in shocked circumstellar gas.
