Rare form of nitrogen detected in comet ISON

Astronomers observed the Comet ISON during its bright outburst in the middle of November 2013. Subaru Telescope’s High Dispersion Spectrograph has detected two rare forms of nitrogen in the comet ISON. Their results support the hypothesis that there were two distinct reservoirs of nitrogen the massive, dense cloud (“solar nebula”) from which our Solar System may have formed and evolved.
