As scientists continue to search for the mysterious Planet Nine in space, two researchers from Queen's University Belfast in Northern Ireland are looking for clues in medieval tapestries.

In 2014, the scientific community began to debate the existence of Planet Nine. For years, most people believed that Pluto was the ninth planet in our solar system, but it was downgraded into a dwarf planet in 2006.

Some scientists believe that Planet Nine's existence would explain the gravitational influence in the distribution of orbits in the Kuiper Belt, a disc in the outer solar system filled with icy remnants from billions of years ago. In 2016, scientists inferred the possible existence of Planet Nine based on modeling work.

Despite the research, no one has been able to see Planet Nine in the skies. There are even some scientists who are skeptical about Planet's Nine existence. Researchers are still scanning the skies to find the planet.

Queen's University Belfast's Marilina Cesario, a medievalist, and Pedro Lacerda, an astronomer, are teaming up to use tapestries and scrolls from the from the Middle Ages to try prove the existence of Planet Nine. They believe that Anglo Saxons might have discovered the planet and recorded their findings in tapestries.
