A recently discovered molecular hydrogen cloud named Eos, located just 300 light-years away from the solar system, has been unveiled using ultraviolet emissions. This crescent-shaped cloud, with a mass equal to 3,400 suns, was previously invisible due to its low carbon monoxide content. The discovery, made possible by the far-ultraviolet instrument on STSAT-1, has opened new possibilities for understanding the molecular universe. Eos lies on the edge of the Local Bubble, providing a safe opportunity to study the evolution of structures in the interstellar medium. The cloud's proximity to the solar system allows for direct observation of how molecular clouds form and evolve, shedding light on galaxy transformation processes. Despite previous beliefs that directly observing molecular hydrogen was challenging, Eos was detected through fluorescence in the far ultraviolet. The researchers plan to expand their search for other molecular hydrogen clouds, aiming to rewrite our understanding of the interstellar medium. With the potential discovery of distant clouds using advanced tools like the James Webb Space Telescope, the study signifies significant progress in unraveling mysteries of the cosmos.
