Astronomers may have already spotted the 'Great Comet of 2026' — and it could soon be visible to the naked eye

We may be less than two weeks into 2026, but a new comet is already leading the charge to become the "Great Comet" of the year. The highly anticipated ice ball, which could potentially be seen with the naked eye, will reach its closest point to us less than four months from now.

Scientists discovered the incoming comet, dubbed C/2025 R3 (PanSTARRS), on Sept. 8, 2025, in images captured by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) — a pair of 5.9-foot (1.8 meters) reflector telescopes located on the summit of Hawaii's Haleakalā volcano. It is currently around 216 million miles (348 million kilometers) from Earth, around halfway between the orbits of Jupiter and Mars, according to TheSkyLive.com.
