French astronaut Thomas Pesquet shared this Saturday on his Instagram account a photograph of the Russian Crimean peninsula taken from space, in which several lakes of shades that vary from pink to teal, turquoise and aqua can be appreciated. .
Color variation is due to different salinity levels in the water, which in turn affects the algae population ‘Dunaliella salina’, which produce substances such as beta carotene.
The more water evaporates, the higher the concentration of this organic pigment that ‘paints’ the lake a reddish hue.
