Discovered last year, the long-period comet may not return for 170,000 years and is thought to have come from the distant Oort Cloud.
Astronomers say such rare visitors offer a brief chance to study icy material preserved from the solar system's formation billions of years ago.
Researchers say planetary gravity could alter its path or even eject it entirely, while observations may shed light on how early building blocks of life reached Earth.
Could this 170,000-year visitor be a messenger from our past, holding the blueprint for life on Earth?
What cosmic secrets has the now-departing 'dirty snowball' comet revealed about our solar system's birth?
Tracking Comet C/2025 R3 (PanSTARRS): Visibility, Fading Brightness, and Its Role as 2026’s Potential “Great Comet”
Overview
As of May 2026, Comet C/2025 R3 (PanSTARRS) is no longer visible for Northern Hemisphere observers, having passed its best viewing window. However, people in the Southern Hemisphere still have a chance to spot the comet in the evening sky, as its movement farther from the Sun makes it somewhat easier to catch. The comet has already passed its peak brightness and is now fading, but with clear skies and binoculars, Southern Hemisphere viewers can still enjoy this celestial event. This changing visibility highlights how a comet’s position and brightness affect observation opportunities around the world.
