We might find aliens in the dust clouds of brown dwarfs, according to a new theory.
Aliens may be living in the dust clouds of brown dwarfs, according to a new study.
Brown dwarfs are substellar objects that have not yet been recognized as a complete star due to insufficient mass to sustain nuclear fusion, which burns hydrogen in the core.
The massive clouds around a brown dwarf have enough energy to support a type of life, but not strong enough to form a new star. These clouds are larger than a planet, smaller than a star, and have a vortex structure.
Experts believe that in the upper atmosphere of the dust clouds, the temperature is as cool as that of Earth. Therefore, this place could be the perfect environment for the existence of microorganisms.
Lead author of the study, Jack Yates, told Science: “It doesn’t have to be a planet with a surface to be inhabited by aliens.”
The team of scientists is currently studying a dust cloud known as WISE 0855-0714, just 7 light-years from Earth.
“While a planet cannot sustain life on its surface, the air around it may be cool enough to sustain life,” they said in the study.
In addition, most of these clouds contain ingredients important for life on Earth such as carbon, hydrogen, nitrogen, and oxygen.
Duncan Forgan, a biologist at the University of St Andrews who was not involved in the study, also said: “This really expands our understanding of how many objects can sustain life.” .
