Pronunciation: [kɒzmˈə͡ʊbɪən] (IPA) 
The word "cosmobion" is spelled with the prefix "cosmo-" meaning "universe" and the suffix "-bion" meaning "life." It is pronounced as /kɒzməʊbaɪən/ with the stress on the second syllable. The "c" is pronounced as /k/ and the "o" as /ɒ/. The "b" at the end of "cosmo" and the "b" at the beginning of "bion" blend together, creating a sound similar to /mb/. The letter "i" is pronounced as /aɪ/ and the final "on" as /ən/.
Cosmobion is a term that refers to a hypothetical organism capable of surviving and thriving in a variety of cosmic environments beyond Earth. It is a combination of the words "cosmic" and "bion," derived from "bios," which means life. The concept of a cosmobion encompasses the notion that life might exist in other parts of the universe, not limited to the conditions found on Earth.
A cosmobion is believed to possess adaptability and resilience, capable of withstanding extreme conditions such as high levels of radiation, extreme temperatures, and low or nonexistent atmospheres. It is postulated that these organisms might have evolved or been created under significantly different environmental conditions compared to life on Earth, making them uniquely suited to survive in alien environments.
The exploration of cosmobions is closely related to astrobiology, which seeks to understand the possibility of life elsewhere in the universe. Scientists speculate that the discovery of cosmobions could play a significant role in expanding our understanding of biology, evolution, and the nature of life itself.
While cosmobions remain purely theoretical at present, ongoing advancements in space exploration technology and the discovery of potentially habitable exoplanets have heightened interest in the existence and characteristics of these extraterrestrial life forms. Studying the potential existence of cosmobions may shed light on the origins of life, the probability of life's existence beyond Earth, and the potential for future human colonization of other planets or celestial bodies.
Any bilateral symmetrically developed organism, as distinguished from one in which the two sides are not symmetrical, i.e. a deformity.
