The Bloom Nebula

Image description:

A microscopic assemblage of cyanobacteria and bloom-forming algae including Gloeotrichia, Anabaena, Microcystis and Woronichinia, captured under fluorescence microscopy using a Zeiss Axiovert 40 inverted microscope. The image reveals the striking, almost celestial geometry of harmful bloom-forming taxa suspended within a single drop of freshwater. Despite their visual beauty, these organisms can have major ecological impacts on aquatic ecosystems, water quality, wildlife and industry.
