An ultra-rare comet is set to be visible from Saudi Arabia this week as it whizzes through the skies — something that only happens every 80,000 years.
Comet C/2023 A3, also known as Tsuchinshan-ATLAS, was first spotted in October last year by Chinese astronomers.
Its long journey through the Oort Cloud, a distant region filled with icy bodies, means this is the first time it's visiting our part of the solar system in recorded human history — an event that has excited both professional astronomers and stargazing enthusiasts alike.
When to see Comet C/2023 A3 in Saudi Arabia
From now until the end of the month, the comet will become visible over Saudi Arabia and the wider region each evening after sunset — with experts suggesting the best date to glimpse the spectacular sight will be Saturday October 19.
Khadijah Ahmad, operations manager of the Dubai Astronomy Group, said: "Comets pass by every now and then, but quite rarely. We don’t know much about this comet and the closer it gets the more we learn. They’re like ancient visitors – relics from the formation of the solar system."
The comet's brilliant tail, formed as it nears the sun and its icy core heats up, will be best viewed just after sunset when it reaches its closest point to Earth.
How to see Comet C/2023 A3 in Saudi Arabia
If you're hoping to catch a glimpse of this celestial spectacle in Saudi Arabia, experts advise finding a spot far from city lights to avoid light pollution, ensuring a clear view of the western horizon.
Binoculars or a small telescope will greatly enhance the view, revealing the comet's glowing nucleus and its long, wispy tail as it streaks across the sky.
For the best experience, plan your stargazing session on October 19, when Comet C/2023 A3 will be at its brightest, and make sure to check local weather conditions for optimal viewing.
Where to see Comet C/2023 A3 in Saudi Arabia
One of the best places to spot the comet will be from AlUla, which earlier this year was officially recognised as the first International Dark Sky Park in Saudi Arabia and the entire GCC region.
As a voluntary program established in 2001, the International Dark Sky Places Program encourages local communities to come together to safeguard their night skies, through responsible lighting practices and public education.
By minimising light pollution, the region protects wildlife habitats, preserves cultural heritage, and supports responsible tourism practices, and encourages the investment in astro-tourism initiatives.
