Asteroid Ryugu's dust reveals nitrogen's slow concentration into complex molecules
Nitrogen is a key ingredient in the biomolecules that form the building blocks of life. Yet as an unbonded gas, it is far more likely to drift into space than to lock itself into solid compounds, making it difficult for astronomers to trace its journey to Earth in the distant past. Through new research published […]
Toru Matsumoto's team discovered nitrogen trapped in two tiny grains of the Ryugu asteroid, reported by the Hayabusa mission.2 These nitrogen molecules – ammonium, carbon-nitrogen bonds and nitrates – should have escaped into space, but they survived millions of years during the evaporation of primitive water.
