AI Summary

The recent discovery suggests that a stellar flyby in the distant past may still be influencing the orbits of long-period comets today. This finding is based on data from the Gaia mission, which has provided researchers with a deeper understanding of the motions of nearby stars. The passage of a star near our solar system could have triggered a significant increase in the number of comets that are ejected from the outer reaches of the solar system. This, in turn, could be responsible for the long-period comets that are observed today. The implications of this discovery are still being explored, but it highlights the complex interactions between our solar system and the surrounding stars.
