A fiery wave from the Sun can rip a comet’s tail clean off—an eerie spectacle we’ve witnessed before—but this time the target is an interstellar visitor, turning a familiar space-weather drama into a once-in-a-generation scientific opportunity that traces directly back to decades of comet–storm forensics and the dawn of interstellar object hunting. How comets became … Read more
The first two interstellar visitors forced a binary narrative: ʻOumuamua as enigmatic and asteroid-like, Borisov as a textbook comet from another star. 3I/ATLAS breaks that mold by combining decisive cometary behavior with an early, coordinated, and instrument-rich observing campaign, shifting the field from reactive puzzling to proactive, system-level science. Trajectories as fingerprints Chemistry resets the … Read more
The call to halt mirror life research has leapt from laboratories to headlines, casting mirror microbes as a civilization-scale hazard that must be preempted now; the wiser move is to distinguish concrete risks from speculative ones and to regulate endpoints, not the entire field. A precise, risk-aware approach can reduce danger while preserving the medical … Read more
Some researchers argue that using a nuclear device to disrupt a Moon-bound asteroid could be the most robust way to reduce broader orbital hazards, but that does not imply a simple green light or turnkey mission. The physics case strengthens under tight timelines and uncertainty, while the legal path, governance precedent, and debris-control demands make … Read more
