A stunning new image of interstellar comet 3I/ATLAS (C/2025 N1 ATLAS) reveals the cosmic visitor's ion tail has grown dramatically longer and more structured — a sign of intensifying activity as it continues its journey through the inner solar system. The image, captured by the Virtual Telescope Project at 11:31 p.m. EDT on Nov. 10 (0431 GMT on Nov. 11), is composed of 18 separate 120-second exposures, remotely taken by robotic telescopes located in Manciano, Italy. Despite the comet being just 14 degrees above the eastern horizon and a bright 61% moon shining about 70 degrees away, a sharply defined, luminous ion tail is seen. "Exploiting the unusual good weather of this season, we imaged the interstellar comet 3I/ATLAS (C/2025 N1 ATLAS) again, recording a much more developed ion tail," Gianluca Masi, Virtual Telescope Project founder and astronomer, said in a post sharing the new image. "Looking at the picture, we see how the ion tail of 3I/ATLAS is clearly showing better and better." An ion tail forms when the sun's ultraviolet radiation strips electrons from gas molecules released by the comet, turning them into charged ions. These ions are then swept away by the solar wind — a constant stream of charged particles flowing outward from the sun — creating a long, often bluish tail that always points directly away from the sun regardless of the comet's direction of travel. This tail differs from the dust tail, which tends to appear yellowish-white and curves gently along the comet's orbital path. In the new image, the comet's bright core is surrounded by a compact coma and a sharply defined ion tail stretching roughly 0.7 degrees across the sky. A faint anti-tail — a feature caused by the observer's perspective as dust trails along the comet's orbit — can also be seen extending in the opposite direction. The image shows a clear increase in activity compared to earlier observations, suggesting that 3I/ATLAS is venting gas and dust more vigorously as it reacts to solar heating. 3I/ATLAS is only the third confirmed interstellar object ever detected, following 1I/'Oumuamua in 2017 and 2I/Borisov in 2019. Unlike its predecessors, this visitor from another star system is bright enough to be studied in detail by ground-based telescopes, offering astronomers a rare opportunity to observe how an interstellar comet behaves under the influence of our sun. The growing length and brightness of the tail suggest increasing sublimation of volatile materials — likely including carbon dioxide and dust — that are then swept into space by the solar wind. Early data suggest that 3I/ATLAS may contain a high fraction of carbon dioxide ice, offering potential clues to the conditions in the distant planetary system where it formed, as well as valuable insight on how comets evolve beyond our solar neighborhood. The Virtual Telescope Project will continue to monitor 3I/ATLAS as it travels through the inner solar system. You can check out past images of the comet taken since it was first detected in July of this year.

ROME, July 21 (Xinhua) -- A proposed new round of tariffs by the United States could result in a 38-billion-euro (44.4 billion U.S. dollars) loss in Italian exports and reduce the country's gross domestic product (GDP) by 0.8 percent by 2027, Italy's largest industrial association said Monday. The findings were published in a report by the research unit of Confindustria, Italy's main business lobby, amid concerns over rising protectionism and its spillover effects on the global economy. U.S. President Donald Trump has threatened to triple a basic tariff on imports from the EU to 30 percent if Brussels does not cut a deal by the end of the month. "A 30-percent tariff would be unsustainable for Italy," the report stated, warning that such a move would not only significantly reduce trade volumes but also have wider macroeconomic consequences. Ciro Rapacciuolo, senior economist at Confindustria's CSC research center, said the tariff could slash Italian exports by 38 billion euros, equivalent to 58 percent of exports to the United States and around 6 percent of Italy's total exports. Under this scenario, Italy's GDP in 2027 would be 0.8 percent lower than projected under a business-as-usual trajectory, the report said. Beyond trade volumes, the tariff plan is also likely to affect exchange rates, inflation trends, and business confidence. According to CSC, the euro has already strengthened against the U.S. dollar in recent months, with the average exchange rate in July reaching 1.17 U.S. dollars per euro, up from a low of 1.04 in January, a 13.3 percent appreciation that could further challenge European exports to the U.S. market. The report also noted that the anticipated market volatility may push the European Central Bank to consider further interest rate cuts, potentially increasing inflationary pressures. Inflation across the eurozone has stabilized in recent months following the price surges seen during the height of the Russia-Ukraine conflict. Data from Italy's national statistics agency ISTAT showed consumer prices in Italy rose 1.7 percent year-on-year in June, compared to 2.0 percent in the broader euro area. Business sentiment remains fragile. Italy's industrial confidence index stood at 93.9 points in June, which was still below the neutral threshold of 100 and indicated subdued optimism among enterprises. The index is likely to decline further if new tariffs are imposed. Confindustria's warning adds to growing international calls urging Washington to reconsider its protectionist stance and return to multilateral approaches in trade policy.
