Usually, nitrogen is considered an \u201cinvisible gas\u201d because it lacks normal spectral  features.&nbsp; Detection of nitrogen would provide a means to characterize the bulk atmosphere of potentially habitable exoplanets and constrain the likelihood of oxygen production by non-living processes.
