New Comet Arrives Over New Zealand This May

Stargazers across New Zealand have a cosmic treat waiting for them in the western sky this month.

Comet C/2025 R3 (PanSTARRS), which recently dazzled viewers in the Northern Hemisphere, has arrived in southern skies. Astrophotographers across Aotearoa have already captured stunning images of the celestial visitor over the past few days, according to Te Whatu Stardome.

Otago Museum astronomer Ian Griffin is excited about viewing what he calls a "bright comet" appearing in the western sky after sunset. The comet sits very low on the horizon for now, requiring viewers to have a clear, unobstructed view to the west.

While the full moon is currently making the comet difficult to spot with the naked eye, conditions should improve. The comet will climb higher into the western sky throughout May, giving more New Zealanders a chance to catch a glimpse.

Stardome recommends looking about an hour after sunset for the best viewing opportunity. Binoculars, a telescope, or a camera will help spot the faint visitor more easily than relying on naked eye observation alone.

For those tracking the comet, the bright star Puanga (also known as Rigel) serves as a helpful guide. The comet is expected to drift higher toward this star over the coming week.

The Bright Side

Amateur astronomers across the country planned to spend Saturday night photographing the cosmic visitor. Griffin hopes the viewing conditions will improve over the next few nights as the comet's position changes.

While the comet will gradually fade in brightness over the coming weeks, May offers a special window for New Zealanders to connect with the wider universe. These rare celestial events remind us that wonder doesn't require traveling far from home.

The night sky is putting on a show, and all Kiwis need is a clear western horizon and a bit of patience to witness it.
