Hubble Space Telescope Observations of the Interstellar Interloper 31/ATLAS
Overview
Paper Summary
Observations of interstellar interloper 3I/ATLAS using the Hubble Space Telescope reveal that the object is smaller than initially estimated, with a nucleus radius less than 2.8 km. The object is active and releasing dust at a rate of 6-60 kg/s, potentially driven by sublimation of ices. The coma morphology suggests anisotropic mass loss predominantly towards the Sun.
Explain Like I'm Five
A space rock from another star system, 3I/ATLAS, is shedding dusty material as it gets closer to the Sun. Scientists used the Hubble telescope to study it and found it's smaller than expected and actively releasing dust.

Rating Explanation
This study provides valuable early observations of an interstellar object, using advanced tools like Hubble. While limitations exist due to data scarcity and necessary assumptions, the findings are significant and advance our understanding of interstellar interlopers. The methodology is sound and the analysis is appropriate given the available data.
