WATCH: Viral Video of Unusual Activity on 3I/ATLAS Sends Social Media Into Meltdown

An astrophotographer known as ‘Chuck’ has captured new images of the interstellar comet 3I/ATLAS on December 2, 2025, prompting renewed discussion on social media. Observers noted that the comet’s coma appeared bright but lacked a visible tail, showing instead a symmetric glow and a clearly defined central point resembling a star. Such characteristics are not typical for comets, leading to speculation about the object’s nature.

Details on 3I/ATLAS

3I/ATLAS was discovered on July 1, 2025, and is the third confirmed interstellar object observed in our solar system, following 1I/ʻOumuamua and 2I/Borisov. It has a hyperbolic trajectory, indicating it will not remain in our solar system. Initial observations had suggested comet-like behavior, with a coma and a subtle green tint due to carbon compounds.

As an object approaches the Sun, it heats up and releases gas and dust from its surface. Recent measurements indicate that 3I/ATLAS may have a nucleus between 440 meters and 5.6 kilometers in diameter. Despite the unusual observations, scientists caution against jumping to conclusions regarding the object’s origins, as many potential natural explanations exist.

Why it matters:

• The ongoing study of 3I/ATLAS can further our understanding of interstellar objects and their behavior in the solar system.
• Public interest and speculation can drive engagement with scientific research and enhance astronomical literacy.

The latest:

• Further scientific analysis is ongoing to investigate the unusual features of 3I/ATLAS and their implications.
