Discovering the secret of life in brown dwarfs

Astronomers from Britain argue that life in the upper atmosphere of brown dwarfs may exist. That is the content of the article published in arXiv.org Electronic Library.

"In order to produce life, it is not necessary to have an Earth-like planet with a solid surface. Since 1976, Carl Sagan has argued that in the top layers of the giant gas planet there could exist organisms - "sails" and "airbag" creatures, absorbing the sun's energy and floating along streams emanating from the deep layers of the planet, " said Jack Yates scientist from the University of Edinburgh (Scotland). determined.

Scientists say that there is life in the highest place of brown dwarf atmosphere .

Brown dwarfs , which the first of its kind found in 1995, are known as astronomers between stars and planets. The weight of such "unconscious" stars is too small to produce a fusion reaction in its own depth. So brown dwarfs gradually turn off and cool.

In recent years, scientists have discovered some incredible properties of brown dwarfs in the presence of weather, lead and "cloud" minerals and other substances. That motivates scientists to the idea that similar stars may be the center of life, such as "sails" and "airbags" that Carl Sagan talked about.

As shown in the calculations, even in the absence of air currents rising from the deep layers of brown dwarfs, the atmosphere of these stars can still exist bacteria, size smaller than typical bacteria on Earth about 10 times.
