Stargazers across the globe are in for a treat this week as the Eta Aquarid meteor shower, one of the most anticipated celestial events of the year, reaches its peak on Tuesday morning.
The Eta Aquarids, which originate from debris left by the famous Halley’s Comet, are expected to produce up to 15 meteors per hour in the Northern Hemisphere under optimal viewing conditions. However, observers in the Southern Hemisphere are set to enjoy a more spectacular show, with up to 50 meteors per hour forecast, according to the International Meteor Organization.
“This is a reminder that Earth is crossing the path of the most famous comet,” said Shauna Edson from the Smithsonian’s National Air and Space Museum. NASA’s meteor expert Bill Cooke described the Eta Aquarids as “pretty fast meteors,” often leaving behind glowing trails of ionized gas, known as meteor trains, rather than bright fireballs.
The meteor shower takes its name from the Aquarius constellation, which is more prominently visible in southern skies. As a result, those living in southern regions will have the clearest view. However, for those in Europe and North America, visibility is still possible, particularly in the early hours before dawn.
The Eta Aquarids are caused by Earth passing through the dusty trail of Halley’s Comet, which only appears in the inner solar system once every 76 years. When this debris enters Earth’s atmosphere at high speed, it burns up, creating the streaks of light commonly referred to as “shooting stars.”
Astronomers advise that no special equipment is needed to enjoy the meteor shower. Instead, they recommend finding a dark spot away from city lights, allowing time for your eyes to adjust to the darkness, and avoiding distractions like phone screens. The best viewing window is in the early morning, before the sky brightens.
However, this year’s display may be partially obscured by a nearly two-thirds full Moon, which could reduce visibility due to its brightness.
The Eta Aquarid shower will remain active until May 28, though the peak display is expected on the morning of April 30. The next major meteor event, the Southern Delta Aquarids, will occur in late July.
Whether watching from the Southern Hemisphere or catching glimpses in the north, skygazers are encouraged to look up and enjoy one of nature’s most captivating light shows.
