The night sky is about to host one of the year’s most anticipated astronomical events. Between the evening of Wednesday, 21 October and the early hours of Thursday, 22 October 2026, Earth will pass through the cloud of icy debris left behind by the famous comet Halley. This crossing marks the peak activity of the Orionids, a meteor shower that promises to light up the heavens with fleeting “shooting stars.”
When the Orionids peak
The shower reaches its maximum intensity during the night of 21 October and the pre‑dawn hours of 22 October. According to astronomer Matías Vidal of the University of Chile’s Astronomy Diploma, the optimal viewing window is between **02:00 and 03:00 a.m.** Local time. At this hour the Moon’s position provides a darker sky, increasing the chance of spotting the meteors.
Why the timing matters
Even though the Earth encounters Halley’s debris throughout the year, the concentration is greatest when the planet’s orbit aligns most closely with the comet’s trail. The early‑morning hours also coincide with the lowest light‑pollution levels in many locations, making it easier for the naked eye to detect the faint streaks that meteors produce.
How to watch – naked eye is best
Experts stress that **no optical aid is needed** – and that telescopes or binoculars are actually counterproductive. “Each meteor can appear anywhere in the sky, and a telescope only shows a tiny portion of the heavens,” explains Vidal. “The best approach is to find a very dark spot, lie back comfortably, and let your eyes sweep a wide area of the sky.”
- Position yourself on a recliner or directly on the ground, looking toward the zenith.
- Avoid urban lights; rural or high‑altitude sites offer the darkest conditions.
- Do not use telescopes or binoculars – they restrict the field of view and reduce the chance of seeing the meteors.
Weather and lunar concerns
Forecasters from Chile’s Meteorological Directorate warn that parts of the central and southern regions may experience **cloudy skies and rain** on the night of the shower. Cloud cover can dramatically reduce visibility, so checking local weather reports is essential. The Moon’s presence in the early part of the night can also wash out fainter meteors, which is why the 02:00–03:00 a.m. window is highlighted as the most promising.
Science behind the shower
The Orionids are born from **Halley’s comet**, a periodic visitor to the inner solar system that completes an orbit around the Sun roughly every 76 years. As the comet approaches the Sun, its icy surface sublimates, releasing dust and rock particles that remain trapped in the comet’s orbital path. Each year, when Earth intersects that path, the particles slam into the upper atmosphere at speeds exceeding 60 km/s, burning up in brilliant flashes. The shower’s name derives from its **radiant** – the point from which the meteors appear to originate – located in the constellation Orion, although the trails can streaked across any part of the sky.
Tips for the best experience
- Plan to be in a location far from city lights and with a clear horizon.
- Arrive before the peak and allow your eyes to adapt to the darkness (this takes about 20–30 minutes).
- Dress warmly, as October nights can be chilly, especially in rural areas.
- Bring a comfortable seat or blanket, and consider a warm drink to stay relaxed while you watch.
