New Horizons Views Wall of Hydrogen Near Edge of Solar System
A massive wall of hydrogen gas has been spotted by astronomers surrounding the solar system. This wall marks the boundary where the solar wind streaming from our Sun becomes overwhelmed by the pressure from random material between the stars. At this point, a visible wall of hydrogen forms as the solar system travels through the galaxy. Researchers from NASA believe they have now seen this wall, in ultraviolet light, using the New Horizons spacecraft.
