Halobacteria:
Halobacteria (also Halobacteriacea) are a class of the Euryarchaeota,[1] found in water saturated or nearly saturated with salt. Halobacteria are now recognized as archaea, rather than bacteria. The name ‘halobacteria’ was assigned to this group of organisms before the existence of the domain Archaea was realized, and remains valid according to taxonomic rules[citation needed]. In a non-taxonomic context, halophilic archaea are referred to as haloarchaea to distinguish them from halophilic bacteria. [Wikipedia]
Noted in the the Research “come on” for Earth to Sky Calculus:
Earth to Sky Calculus has been conducting research into the stratosphere since 2010. Their work has resulted in cutting-edge findings on halobacteria, cosmic radiation and other conditions 100,000 feet about Earth.
