TLDR: Interstellar comet 3I ATLAS is emitting water at an unprecedented rate of 1.6 kilograms per second, challenging previous assumptions about comet behavior. This high water output, linked to surface heating as it approaches the Sun, prompts further investigation into the characteristics and origins of interstellar comets.



Recent observations of the interstellar comet 3I ATLAS have revealed that it is emitting water at an astonishing rate, likened to a fire hose running at full blast. This discovery has significant implications for our understanding of cometary behavior and the composition of interstellar objects.

Scientists have found that 3I ATLAS, which was discovered in 2019, is not only a visitor from beyond our solar system but also a source of considerable water output. This comet is releasing water vapor at a rate of around 1.6 kilograms per second. Such a high emission rate is unprecedented and challenges previous assumptions about how interstellar comets behave and interact with solar radiation.

The research team utilized data from several observatories to analyze the comet's activity. It was determined that the water being expelled is likely the result of the comet's surface heating up as it approaches the Sun. This warming triggers the sublimation of ice, sending water vapor streaming into space.

This phenomenon is particularly intriguing because it suggests that interstellar comets may have different characteristics compared to those originating within our solar system. The findings prompt further investigation into the composition of these celestial travelers and their potential role in delivering water—and possibly even organic materials—to planets.

Understanding the behavior of 3I ATLAS may also provide clues about the early solar system and the processes that led to the formation of planets. As researchers continue to study this remarkable object, they hope to uncover more about its origins and the broader implications for our knowledge of interstellar objects.

This discovery not only adds to the growing body of knowledge about comets but also emphasizes the importance of ongoing astronomical research. As technology advances, scientists are better equipped to observe and analyze these distant visitors, revealing the secrets of the universe one comet at a time.
