Saskatchewan residents are in for a celestial treat! For just a few more days, the rare Comet Tsuchinshan-Atlas will illuminate the western skies at dusk, providing a once-in-a-lifetime opportunity for skywatchers to see this breathtaking phenomenon without the aid of telescopes.

Originating from the mysterious Oort Cloud—an icy region located far beyond Pluto—Comet Tsuchinshan-Atlas made its closest approach to Earth, about 44 million miles (71 million kilometers) away. This incredible visitor is not expected to return for another 80,000 years, making this a must-see event for anyone interested in astronomy, assuming it survives its journey through space.

While many comets are detected annually, most either disintegrate when nearing the Sun or drift too far away to capture our attention. According to Larry Denneau, a leading researcher at the Atlas telescope responsible for the comet's discovery, Tsuchinshan-Atlas stands out due to its welcome visibility.

“What you’re witnessing is truly special,” says Ron Waldron, a member of the Royal Astronomical Society of Canada based in Saskatoon. “Comets are often described as ‘dirty snowballs’ because they’re composed of ice, dust, and gas. As they get closer to the Sun, the ice sublimates—turning directly from solid to gas—resulting in the beautiful tail that we're all excited to see.”

The tail of Comet Tsuchinshan-Atlas stretches an astounding one million kilometers long, an impressive sight for those looking skywards. Just a few nights ago, a local skygazer shared a stunning photo of the comet, capturing its majestic presence.

However, viewers should act quickly; Comet Tsuchinshan-Atlas will gradually fade as it climbs higher in the night sky. “You’ll want to catch it soon, as it’s going to get dimmer every night,” Waldron warned.

For the best chance to see this cosmic wonder, head outside around 7:30 p.m and look west just after dusk. Make sure you have an unobstructed view of the horizon and try to escape light pollution for optimal viewing.

Comets might come and go, but it's not every day that one appears visible to the naked eye. The last comet to grace our skies without needing a telescope flew by in August 2020, making this event particularly exciting.

The excitement doesn’t stop with the comet; recent weeks have also blessed residents with vibrant displays of the aurora borealis, and skywatchers are in for more stunning sights. Waldron reveals that we’re on the cusp of an extraordinary winter for auroras, with increased brightness expected as we head into next year. This surge in activity is due to the Sun's 11-year solar cycle hitting its peak, which will generate fantastic solar storms that enhance the northern lights.

So grab your friends or family, venture outside, and relish in the wonders of the universe before Comet Tsuchinshan-Atlas makes its exit. Who knows when you’ll have another chance like this again!
