Galaxies of Genetically Modified E. coli

Zachary Copfer, the same bioartist behind those bacterial radiograph portraits of famous scientists, also created a series of galaxies drawn with E. coli expressing fluorescent proteins.

Here are his bacteriastronomical renditions of the Milky Way and M81 galaxies. Bacteria, some of the oldest life forms on our planet, recreating the star stuff they were seeded from, a pretty neat reminder that even in our individual bodies they are as numerous as the stars in a galaxy.
