Astronomers may have finally uncovered new Planet 9 evidence — a massive, unseen world lurking far beyond Neptune. The planet was detected in two infrared sky surveys taken 23 years apart, where a faint moving dot shifted just enough to suggest something extraordinary. If confirmed, it could be larger than Neptune and orbit the Sun at a distance 700 times greater than Earth.<br />In this video, we explore the full story behind this solar system mystery — how scientists connected decades of sky data, what makes Planet 9 so controversial, and why it could redefine our understanding of the outer solar system. Stay tuned as we break down what astronomers believe might be the most important space discovery of the decade.
