PanSTARRS comet: Rare celestial event set to light up skies — here’s how and when to watch

A newly discovered comet, C/2025 R3 (PanSTARRS), is capturing global attention as it brightens in the night sky, offering stargazers a rare opportunity to witness a cosmic traveler that may not return for thousands of years.

Discovery and cosmic origins

The comet, formally called C/2025 R3 (PanSTARRS), was discovered only in September 2025 by the Pan-STARRS telescopes in Hawaii. Since then, it has been traveling across the Earth’s solar system, gradually becoming brighter.

Astronomers indicate that this ancient object may orbit the Sun approximately every 170,000 years. Some experts, citing reports from Forbes and Space.com, believe it could originate from the distant Oort Cloud, a massive zone filled with icy debris at the fringes of our solar system.

Why the comet is getting brighter

As it continues its journey, the comet has significantly brightened and developed a visible tail, increasing the chance that it might be seen without optical instruments instead of only through telescopes or binoculars.

Astronomers cite that the comet has been steadily intensifying since its discovery and is expected to deliver its most impressive display in April as it nears both the Sun and Earth.

Important dates to watch

• April 17, 2026: One of the best opportunity to observe the comet
  
• April 19, 2026 (Perihelion): Nearest point to the Sun
  
• April 27, 2026: Closest approach to Earth
  

As per NASA's skywatching guide, the comet will come within almost 44 million miles of Earth, around half the distance between Earth and the Sun. Some estimates position this distance at approximately 45.5 million miles (73.2 million km).

Where and how to see it

The comet is anticipated to remain visible throughout much of April before sunrise in the Northern Hemisphere. Observers should look toward the eastern sky, mainly above the constellations:

• Pegasus
  
• Pisces
  

For the best viewing experience:

• Scan the lower eastern sky 90 minutes to two hours before sunrise
  
• Choose a dark place with minimal light pollution
  
• Use binoculars or a telescope, even though it may be faintly visible to the naked eye
  

According to EarthSky.org, while naked-eye viewing is possible, optical tools will greatly enhance clarity. Current brightness estimates rate the comet at around magnitude 4.6.

Southern Hemisphere visibility

Observers in the Southern Hemisphere may have to wait a bit longer. The comet is expected to appear low on the western horizon following sunset in late April, with viewing conditions improving in early May as it rises higher in the sky.

Why this event matters

This comet’s relatively close pass moving between Earth and the Sun makes it particularly significant. Due to its brightness and path, it has already been described as one of the most notable skywatching events of 2026, especially for early-morning viewers.
