Mars' oddest cloud may be even odder than previously thought

What happened

Scientists using the European Space Agency's Mars Express, in combination with a state-of-the-art meteorological model of the Red Planet, have found that there may be some exotic physics behind Mars' most curious cloud. The paper, "Homogeneous ice Nucleation from Water Vapour Suggested by Elongated Clouds on Mars," is published in Nature Geoscience.
