Golden Comet C/2025 K1 (ATLAS) Shines After Sun Encounter

Comet C/2025 K1 (ATLAS) displays a surprising golden glow after its closest approach to the sun. Its unique coloration, attributed to a lack of carbon particles, sets it apart from other comets like Nishimura and 3I/ATLAS.

New pictures show that the lately found comet C/2025 K1 (ATLAS) established a surprising golden radiance after reaching its closest point to the sunlight. Until now, the comet has gone under the radar, mainly thanks to the more well-known interstellar comet 3I/ATLAS.

Unexpected Golden Radiance

C/2025 K1 reached its closest point to the sun, or perihelion, on Oct. 8, coming within a minimal range of 31 million miles (50 million kilometers) of our home star– around four times closer than 3I/ATLAS managed throughout its own perihelion on Oct. 29. Due to the extreme gravitational strain from this close experience, several experts believed that C/2025 K1 would certainly be torn apart, according to Spaceweather.com.

Absence of Carbon Compounds

New images reveal that a lately found comet dubbed the “various other ATLAS” has changed right into a stunning golden ribbon after enduring a close method to the sunlight– a trip that numerous professionals thought would be the comet’s ruin.

In a current blog post, astronomer David Schleicher, that has been examining C/2025 K1 from the Lowell Observatory in Arizona, created that the comet has an unexpected absence of carbon-bearing particles, such as dicarbon, carbon monoxide and cyanide. Just two various other known comets have ever had fewer of these particles, he created.

Comet’s Unique Coloration

“This comet was not intended to survive its Oct. 8th perihelion,” Bartlett told Spaceweather.com. “Yet it did survive, and now it is displaying a red/brown/golden color rarely seen in comets.” The exact same one-of-a-kind coloration was observed by a minimum of two various other professional photographers, in California and in Arizona.

Comets typically show up white since the sunlight they reflect includes all the wavelengths of noticeable light. When specific chemicals are existing within the cloud of dust, ice and gas surrounding the comet, known as the coma, they can absorb specific wavelengths of light, causing the comet to shine with a different shade.

On Oct. 29, at the same time 3I/ATLAS achieved perihelion, astrophotographer Dan Bartlett broke a magnificent shot of C/2025 K1 from June Lake in California. The image shows the comet with a distinctive golden radiance and a lengthy tail that appears it has been buffeted by the solar wind– comparable to Comet Lemmon, which just recently had its tail torn to pieces.

Viewing the Golden Comet

He covers a large variety of subjects including room expedition, global science, area weather, climate change, animal actions and paleontology. He additionally writes Live Science’s once a week Planet from room collection.

If you intend to see it on your own, C/2025 K1 is located between the constellations Virgo and Leo in the eastern skies, and it is most plainly visible shortly before dawn, according to Spaceweather.com. It will certainly reach its closest indicate Planet on Nov. 25, indicating it will likely stay noticeable till early December.

Other Comets’ Colors

This exhaustion of carbon-bearing molecules is the most likely cause for the comet’s gold coloration, yet “we do not know exactly why,” Spaceweather.com representatives wrote. It might also have something to do with its current solar flyby or its relatively low ratio of gas to dirt, they included.

New photos of the “various other” ATLAS comet, C/2025 K1 (ATLAS), reveal that it has created a golden glow after passing its closest factor to the sun.” This comet was not meant to survive its Oct. 8th perihelion,” Bartlett informed Spaceweather.com. A number of remarkable comets have actually turned green in current years– including Comet Nishimura, the explosive “evil one comet” 12P/Pons-Brooks and the aptly named “green comet” C/2022 E3– due to the presence of either dicarbon or cyanide in their corresponding comas. Some comets can additionally transform blue if their comas consist of carbon monoxide or ammonia, which may be happening to 3I/ATLAS, according to current observations. He also writes Live Scientific research’s regular Planet from space series.

Numerous noteworthy comets have actually transformed environment-friendly in current years– consisting of Comet Nishimura, the explosive “adversary comet” 12P/Pons-Brooks and the appropriately called “environment-friendly comet” C/2022 E3– due to the visibility of either dicarbon or cyanide in their corresponding comas. Some comets can likewise transform blue if their comas contain carbon monoxide or ammonia, which may be occurring to 3I/ATLAS, according to recent monitorings. Nevertheless, the gold shade of C/2025 K1 is much rarer.
