The Moon this year

It is a new Moon, so the sky is as dark as it gets. A very good year.

About the Eta Aquariids

The Eta Aquariids are debris from Halley's Comet. They are best from the southern hemisphere and the tropics, where the radiant climbs high before dawn. From central Europe the radiant rises only shortly before sunrise, so you see a handful of long meteors skimming up from the horizon.

Where to look

The meteors seem to fly out of a point in Aquarius, the radiant, but they can appear anywhere in the sky. Look about halfway up, at a wide area of sky away from the Moon and street lights, and give your eyes 20 minutes to adjust to the dark.

How to watch

  • Get away from town lights if you can. A dark sky shows several times as many meteors.
  • Lie back on a mat or a reclining chair, so you can watch a big piece of sky without craning your neck.
  • Keep your phone away, or use a red screen: one glance at a bright screen undoes your night vision.
  • Dress warmly and be patient. Meteors come in bursts, with quiet spells in between.

Quick answers

When is the best time to see the Eta Aquariids?

On the night of 5–6 May 2027, before dawn, from somewhere dark. The shower is active for several nights around the peak, so the nights either side are worth a look too.

How many Eta Aquariids meteors will I see?

The rate at the peak is about 50 an hour under a perfect, dark sky with the radiant overhead. In practice expect a third to half of that, and fewer from a town or with the Moon up.

Do I need a telescope or binoculars?

No. Meteors are best with your eyes alone: they flash across a wide area of sky, far too fast for a telescope. Lie back and take in as much sky as you can.

Where do the Eta Aquariids come from?

They are dust from Halley's Comet (1P/Halley). Earth runs through its trail of debris at the same time every year, and the grains burn up about 100 km above us at 66 km/s.
