Delta Aquariid Meteor Shower 2024

Delta Aquariids
This year, the Delta Aquariid meteor shower is active from 12 July to 23 August. The shower doesn’t have a noticeable peak, but its expected to reach its maximum rate on 30 July.
The radiant of this meteor shower appears to come from near the star Delta Aquarii in the constellation Aquarius. The radiant will rise above the horizon in the late evening and will reach its highest point above the southern horizon around 3:00am the following morning and will have a steady stream of 15-20 meteors per hour at its peak in ideal conditions. Light from the waning crescent moon which rises around 1:00am may interfere with your meteor-gazing efforts.
What is a Meteor Shower?
Meteor showers occur when the Earth passes through the debris of a comet. The dust and gas left behind by the comet burn up in the atmosphere causing a shooting star.
The Delta Aquariids meteor shower likely comes from the comet 96P/Machholz. It is estimated to be 6.4 kilometres in diameter and takes just over five years to complete an orbit of the Sun. This comet is known as a sungrazing comet, which is where the comet can get within 1,400,000 kilometres of the Sun on its closest approach.
How to Watch from the UK
To watch the Delta Aquariid meteor shower, face towards the south-east and scan the skies. Whilst the peak is predicted to occur during the early evening, the skies will still be light and the radiant in the constellation of Aquarius won’t have yet risen above the horizon. This is where the meteors will appear to radiate from, but make sure you look at the whole sky as they can appear all over.
The meteor shower is expected to peak in the early hours just after midnight when the radiant will be higher up in the sky. Find Aquarius by looking for the square of Pegasus in the south-east, then look down towards the horizon and you will see a bright star. This isn’t actually a star – it’s Saturn positioned in the constellation on Aquarius.
There are also other astronomical objects to spot around this time. To the left of the square of Pegasus you may be able to see a faint smudge - this is the Andromeda Galaxy! This is a great deep sky object to look at through binoculars or a telescope. Close to the waning crescent Moon you will be able to see Mars which rises around 01:00 and Jupiter which rises shortly after.
So, find a dark sky area, wrap up warm, and allow at least 20 minutes for your eyes to adjust to the low light conditions and scan the skies to enjoy the shooting stars using just the optical tool nature gave you – your eyes!
