A time-lapse animation of satellite pictures, showing Lonar crater lake changing its color from a green to a reddish pink in a span of 3 days in June 2020.
Reports by Agharkar Research Institute, National Environmental Engineering Research Institute and Geological Survey of India suggested that lowered water levels and high salinity caused growth of Halobacterium and increased Carotenoid levels, which in turn led to color change.

Video of a solar filament of a coronal mass ejection being launched. Filaments are thread-like dense, somewhat cooler, clouds of material that are suspended above the solar surface by loops of magnetic field. Filaments can erupt fully or partially and these erupted material can be observed in form of coronal mass ejections which can collide with Earth's magnetosphere, where they can cause geomagnetic storms, aurorae, and in rare cases damage to electrical power grids.
