The Eos Cloud is a dark molecular cloud of Hydrogen gas located just 94 parsecs from the Sun near the edge of the Local Bubble. The cloud has a small amount of Carbon Monoxide contained within it.[1] It is predicted that in 5.7 million years, the Eos cloud will photoevaporate.[2][3]
The cloud was discovered in the year 2025 by using H2 far ultraviolet fluorescent line emission. Its close proximity (one of the closest clouds to Earth) to Earth allows for easier observation of how theses molecular clouds form and dissipate.[1]
