<ul><li>Research led by Samantha Hemmelgarn at Northern Arizona University focuses on using meteor showers to locate long-period comets.</li><li>Long-period comets, with orbits longer than 200 years, are difficult to detect until they're dangerously close to Earth.</li><li>The study developed a model that connects meteor showers to their parent comets, allowing astronomers to trace the comets' locations in space.</li><li>By using telescopes to locate these hidden comets early, scientists can better prepare for potential impacts and mitigate risks.</li></ul>
