Page 5: 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.

Could the latest 'interstellar comet' be an alien probe?

On July 1, astronomers spotted an unusual high-speed object zooming towards the sun. Dubbed 3I/ATLAS, the surprising space traveler had one very special quality: its orbit showed it had come from outside our solar system.
