Astronomer Avi Loeb is spotlighting an unusual spaceflight idea: using interstellar objects as the basis for future spacecraft. In a Medium post, he revisits the discovery of three large interstellar visitors over the past decade and frames them as more than scientific curiosities.
The article links the scale of these objects to a familiar reference point, noting that they were larger than a soccer field. With attention on the World Cup final on July 19, 2026, that comparison gives readers an easy way to picture the size of these rare bodies as they pass through or near our cosmic neighborhood.
Loeb’s broader theme is that naturally occurring objects from outside the solar system could one day be studied not just for what they reveal about distant planetary systems, but also for how they might be used. The concept points to a future in which astronomy and space engineering overlap, turning incoming interstellar material into practical tools for exploration.
While the idea remains speculative, it reflects a growing interest in how humanity might respond to newly detected objects from beyond the solar system. As more interstellar visitors are found, discussions like Loeb’s suggest they may shape both scientific research and long-term thinking about travel in space.
