A spectacular cosmic event is set to unfold this week as the “comet of the century” graces the skies. Comet A3 (Tsuchinshan-Atlas), which last visited the solar system 80,000 years ago, is making its way past Earth in what astronomers are hailing as a rare and remarkable occurrence.
Discovered in January last year, the comet is now becoming visible to the naked eye as it approaches the Sun. Stargazers are in for a treat as the comet is expected to be visible in two windows, subject to favourable weather conditions and minimal light pollution. The first window, between 27 September and 2 October, will showcase the comet in the eastern sky just before sunrise, while the second window, from 12-30 October, will offer views in the western sky just after sunset.
The brightness of the comet remains uncertain, with its closest encounter with Earth set for 12-13 October. Even from the vantage point of the International Space Station, Nasa astronaut Matthew Dominick described the comet as resembling a “fuzzy star,” anticipating stunning images as it approaches the Sun.
While some anticipate this to be a once-in-a-lifetime opportunity to witness a comet, others have tempered expectations. Dr. Robert Massey from the Royal Astronomical Society expressed enthusiasm for the event, cautioning against expecting a celestial spectacle on par with past comets. He suggested scanning the skies with binoculars to spot the comet, which the Royal Astronomical Society will also provide charts for guidance.
For those unable to witness the comet firsthand, a live stream of the event will be hosted by the Virtual Telescope Project on 9 October, capturing the celestial wonder from their observatory in Manciano, Italy.
As the “comet of the century” dazzles the night sky, skywatchers around the world are gearing up for a momentous occasion that promises to inspire wonder and awe in all who witness its celestial beauty.
