Astronomers have discovered a massive, crescent-shaped cloud named Eos, filled with hydrogen, which is the closest known cloud to Earth and has the potential to form stars. This discovery could reshape astronomers' understanding of star and planet formation in our galaxy.
Key Points
Eos is a colossal cloud filled with hydrogen, located 300 light-years from Earth
Eos is the closest known cloud to Earth and is as wide as 40 Earth's moons
Discovery of Eos could help measure creation and destruction rates of fuel for star formation
Eos is the first molecular cloud detected using the fluorescent nature of hydrogen
Pros
Potential to reshape understanding of star and planet formation
Provides insight into hidden reservoirs of hydrogen in our galaxy
Could lead to the discovery of more hydrogen-heavy clouds
Cons
Difficulty in detecting molecular hydrogen from the ground
