River of hydrogen flowing through space seen with Green Bank Telescope

Using the National Science Foundation’s Robert C. Byrd Green Bank Telescope, 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.
