River of Hydrogen Flowing through Space Seen with Green Bank Telescope


National Radio Astronomy Observatory said:

Using the National Science Foundationís Robert C. Byrd Green Bank Telescope (GBT), astronomer D.J. Pisano from West Virginia University has discovered what could be a never-before-seen river of hydrogen flowing through space. This very faint, very tenuous filament of gas is streaming into the nearby galaxy NGC 6946 and may help explain how certain spiral galaxies keep up their steady pace of star formation.
