About half of present-day cloud condensation nuclei originate from atmospheric nucleation, frequently appearing as a burst of new particles near midday. Atmospheric observations show that the growth rate of new particles often accelerates when the diameter of the particles is between one and ten nanometres. In this critical size range, new particles are most likely to be lost by coagulation with pre-existing particles, thereby...

Scientists say early Earth’s atmosphere would have left us light-headed
First spectral analysis of a super-Earth’s atmosphere shows it’s not super for life
For the first time, astronomers have conducted a spectral analysis of a distant super-Earth’s atmosphere – and the results show it would be a hellish place to visit. We already knew that about 55 Cancri e, which...
