Preface: Many people develop a strong interest in science and space when they gaze at the stars at nightfall. The boundless potential of human thought and imagination holds limitless possibilities, and young people are eager to explore this realm. In fact, everyone possesses.
Background: Interstellar comet 3I/ATLAS aligns with the Sun-Earth axis on January 22, 2026, offering scientists what researchers describe as a once-in-decades opportunity to study pristine material from another star system.
At solar opposition, the anti-tail jet will be pointing at Earth, said Professor Avi Loeb.

Solar Radiation Storm Forecast for Jan 20-Jan 22 2026 Jan 20 Jan 21 Jan 22 S1 or greater 99% 95% 65% Rationale: An S2 (Moderate) solar radiation storm is in progress at the time of this summary. S1 (Minor) radiation levels are expected on 21-22 Jan.
My imagination: If 3I/ATLAS’s “anti-tail” point to earth. Coincidentally 22nd JAN 2026 earth magnet field defense strong solar wind from Sun. Assume the magnetic have chance intercept with 3I/ATLAS anti-tail. Because 3I/ATLAS’s “anti-tail” (a sunward extension of its coma) and unusual chemical composition are linked to the sublimation of volatile compounds, especially carbon dioxide (CO2cap C cap O sub 2𝐶𝑂2), methanol, hydrogen cyanide (HCN), and potentially organometallic molecules like nickel carbonyl, which vaporize to create jets and unusual dust pattern. It is strong. In this scenario. Does it have change in earth atmosphere?
If the anti-tail of 3I/ATLAS points towards Earth, and Earth’s magnetic field happens to resist the strong solar wind from the Sun on January 22, 2026, let’s assume the magnetic field encounters the anti-tail of 3I/ATLAS. Since the anti-tail of 3I/ATLAS (the portion of its coma extending towards the Sun) and its anomalous chemical composition are associated with the sublimation of volatile compounds, particularly carbon dioxide (CO₂), methanol, hydrogen cyanide (HCN), and potential organometallic molecules (such as nickel carbonyl), these substances would vaporize to form jets and unusual dust distribution. In this scenario, would Earth’s atmosphere change?
A magnetic field promotes the adsorption of CO2 and H2 onto the surface of magnetized catalysts. This facilitates the reaction between CO2 and hydrogen to produce methanol. If methanol located in space and approach of the outer layer of atmosphere? What is the impact?
If methanol located in space were to approach Earth’s outer atmosphere, its impact would be defined by rapid chemical breakdown and atmospheric heating rather than direct environmental contamination. Does it mean the earth temperature increased?
Yes, if methanol from space were to enter the atmosphere, it would contribute to a rise in Earth’s temperature, though primarily through indirect chemical pathways rather than the heat generated during its entry.
Despite these warming effects, Earth has natural “sinks” that limit methanol’s impact:
- Short Lifetime: Methanol only stays in the atmosphere for about 5 to 12 days.
- Oceanic Absorption: The ocean acts as a major “sink,” quickly absorbing and depositing methanol that reaches lower altitudes, which helps mitigate its long-term warming effect.
Therefore, we can safely observe this astronomical phenomenon.
