Page 4: Research news on Interstellar objects

Interstellar objects as a research area focus on the detection, characterization, and dynamical analysis of solid bodies that originate outside a planetary system and traverse or enter another, such as the Solar System. This field integrates observational astronomy, celestial mechanics, planetary science, and astrochemistry to constrain their trajectories, compositions, sizes, shapes, rotational states, and possible formation environments. Research investigates their implications for planetesimal formation, mass loss from planetary systems, galactic dynamical processes, and the transfer of material between stellar systems, as well as optimizing observational strategies and instrumentation for their rapid identification and follow-up before they exit observational reach.

What technosignatures would interstellar objects have?

The recent discovery of the third known interstellar object (ISO), 3I/ATLAS, has brought about another round of debate on whether these objects could potentially be technological in origin. Everything from random YouTube ...

JWST reveals 3I/ATLAS's coma is largely carbon dioxide

All (or at least most) astronomical eyes are on 3I/ATLAS, our most recent interstellar visitor that was discovered in early July. Given its relatively short observational window in our solar system, and especially its impending ...

Hubble captures stunning view of third interstellar visitor

Astronomers using the Hubble Space Telescope have observed 3I/ATLAS, only the third known object from outside our solar system to visit our neighborhood. This interstellar interloper is putting on quite a show as it approaches ...
