Summary
- Comet C/2025 R3 PanSTARRS is currently visible in southern skies.
- Binoculars or telescopes are needed to observe its blue-green glow.
- The comet returns after a 170,000-year journey around the sun.

A rare celestial visitor, comet C/2025 R3 PanSTARRS, is currently visible in the southern hemisphere's night sky. Stargazers have a limited two-week period to observe this comet, which will not be seen again for approximately 170,000 years. This long-period comet, discovered in 2025, originates from the distant Oort Cloud.
While not bright enough for naked-eye viewing, the comet can be observed with binoculars or a telescope. Viewers can expect to see a blue-green orb, known as a coma, and a faint, smudgy tail. The best viewing time is in the hour after sunset, low on the western horizon. Comet PanSTARRS is gradually decreasing in brightness, urging interested individuals to capture its appearance soon.
The comet's trajectory is difficult to predict due to mass loss as it orbits the sun, meaning it might be ejected from the solar system entirely. Its return is estimated to be around 170,000 years, provided it doesn't disintegrate before completing its vast journey.
