Why do both Earth and Titan---two very dissimilar bodies---possess thick atmospheres dominated by molecular nitrogen? The answer begins with evidence for N2 as the principal form of nitrogen in the solar nebula. This evidence is based on the measurement of 15N/14N on Jupiter, buttressed by recent measurements of this isotope ratio in high temperature inclusions in chondritic meteorites. Perhaps paradoxically these data show that Earth's nitrogen did not arrive as N2, but as readily condensable nitrogen compounds such as ammonia. That Titan's atmospheric nitrogen had a similar source is strongly suggested by the absence of detectable amounts of krypton and xenon in the satellite's atmosphere. Recently recorded data on the nitrogen abundance and isotope ratios in comets provide further support for this conclusion.
