The NASA New Horizons spacecraft's extensive observations of Lyman-alpha emissions have resulted in the first-ever map from the galaxy at this important ultraviolet wavelength, providing a new look at ...
A Lyman-alpha emission is of the wavelength represented here as Lyman-alpha line. When gas is outflowing, the Lyman-alpha emission shifts into the longer, redder wavelength. The opposite occurs when ...
