A rare celestial event is captivating skywatchers across the globe as Comet C/2024 G3 (Atlas) becomes potentially visible for the first time in 160,000 years.
NASA has hinted at the possibility of the comet being bright enough to be seen with the naked eye, though the agency has cautioned that predicting a comet’s brightness is “notoriously hard.”
The closest approach to the Sun sparks excitement
The comet reached perihelion on Monday, marking its closest approach to the Sun, a factor that greatly influences its brightness. Experts suggest that sightings may begin as early as Monday night, though exact visibility depends on local conditions.
Astronomers believe the best chance of spotting the comet may be in the southern hemisphere, where it could shine as brightly as Venus.
A “sun-skirting” comet
The comet was discovered last year by NASA’s Asteroid Terrestrial-impact Last Alert System (ATLAS). Dr. Shyam Balaji, a researcher in astroparticle physics and cosmology at King’s College London, explained, “Current orbital calculations indicate it will pass about 8.3 million miles from the Sun,” classifying it as a “sun-skirting” comet.
The university described the event as a once-in-160,000-years opportunity, emphasizing the rarity of such sightings.
Viewing tips for stargazers
Dr. Balaji offered guidance for those hoping to catch a glimpse of the comet:
- Southern hemisphere: Look toward the eastern horizon before sunrise, and after perihelion, shift focus to the western horizon after sunset.
- Northern hemisphere: Observing may be more challenging due to the comet’s relative position to the Sun, but attempts can still be made.
Dr. Balaji advised heading to areas free from light pollution and using binoculars or a small telescope for a better view. He also warned observers to exercise caution around sunrise and sunset while tracking the comet’s position.
NASA shares stunning comet image
Astronomers and space enthusiasts have been closely following the comet’s path. On Saturday, NASA astronaut Don Pettit shared a breathtaking photograph of Comet C/2024 G3 (Atlas) captured from the International Space Station.
“It is totally amazing to see a comet from orbit. Atlas C2024-G3 is paying us a visit,” Pettit wrote on social media.
Unpredictable yet awe-inspiring
Despite predictions of brightness, Dr. Balaji noted that comet visibility is “notoriously uncertain,” as many comets often appear dimmer than initially expected.
For those eager to witness this rare spectacle, clear skies and proper planning will be essential. Check local weather conditions and prepare to marvel at this once-in-a-lifetime celestial visitor.
